+```
+
+**Error Responses:**
+
+- `400 Bad Request`: Invalid provider name
+- `422 Unprocessable Entity`: Invalid parameter type
+- `500 Internal Server Error`: Database or processing error
+
+---
+
+## Security & Validation
+
+### Input Validation
+
+1. **Hours Parameter:**
+   - Server-side clamping: `1 <= hours <= 168`
+   - Invalid types rejected with `422 Unprocessable Entity`
+   - Out-of-range values automatically clamped (no error)
+
+2. **Providers Parameter:**
+   - Allow-list enforcement: Only valid provider names accepted
+   - Max 5 providers enforced (excess silently truncated)
+   - Invalid names trigger `400 Bad Request` with detailed error
+   - SQL injection prevention: No raw SQL, parameterized queries only
+   - XSS prevention: Input sanitized (strip whitespace)
+
+3. **Rate Limiting (Recommended):**
+   - Implement: 60 requests/minute per IP for chart routes
+   - Use middleware or reverse proxy (nginx/cloudflare)
+
+### Security Measures Implemented
+
+✓ Allow-list validation for provider names
+✓ Parameter clamping (hours: 1-168)
+✓ Max provider limit (5)
+✓ SQL injection prevention (ORM with parameterized queries)
+✓ XSS prevention (input sanitization)
+✓ Comprehensive error handling with safe error messages
+✓ Logging of all chart requests for monitoring
+✓ No sensitive data exposure in responses
+
+### Edge Cases Handled
+
+- Empty provider list → Returns default providers
+- Unknown provider → 400 with valid options listed
+- Hours out of bounds → Clamped to [1, 168]
+- No data available → Returns empty series or 999.0 staleness
+- Provider with no rate limit → Returns null limit_value
+- Whitespace in provider names → Trimmed automatically
+- Mixed valid/invalid providers → Rejects entire request
+
+---
+
+## Testing
+
+### Automated Tests
+
+Run the comprehensive test suite:
+
+```bash
+# Run all chart tests
+pytest tests/test_charts.py -v
+
+# Run specific test class
+pytest tests/test_charts.py::TestRateLimitHistory -v
+
+# Run with coverage
+pytest tests/test_charts.py --cov=api --cov-report=html
+```
+
+**Test Coverage:**
+
+- ✓ Default parameter behavior
+- ✓ Custom time ranges (48h, 72h)
+- ✓ Provider selection and filtering
+- ✓ Response schema validation
+- ✓ Percentage range validation [0-100]
+- ✓ Timestamp format validation
+- ✓ Status derivation logic
+- ✓ Edge cases (invalid providers, hours clamping)
+- ✓ Security (SQL injection, XSS prevention)
+- ✓ Performance (response time < 500ms)
+- ✓ Concurrent request handling
+
+### Manual Sanity Checks
+
+Run the CLI sanity check script:
+
+```bash
+# Ensure backend is running
+python app.py &
+
+# Run sanity checks
+./tests/sanity_checks.sh
+```
+
+**Checks performed:**
+
+1. Rate limit history (default params)
+2. Freshness history (default params)
+3. Custom time ranges
+4. Response schema validation
+5. Invalid provider rejection
+6. Hours parameter clamping
+7. Performance measurement
+8. Edge case handling
+
+---
+
+## Performance Targets
+
+### Response Time (P95)
+
+| Environment | Target | Conditions |
+|-------------|--------|------------|
+| Production | < 200ms | 24h / 5 providers |
+| Development | < 500ms | 24h / 5 providers |
+
+### Optimization Strategies
+
+1. **Database Indexing:**
+   - Indexed: `timestamp`, `provider_id` columns
+   - Composite indexes on frequently queried combinations
+
+2. **Query Optimization:**
+   - Hourly bucketing done in-memory (fast)
+   - Limited to 168 hours max (1 week)
+   - Provider limit enforced early (max 5)
+
+3. **Caching (Future Enhancement):**
+   - Consider Redis cache for 1-minute TTL
+   - Cache key: `chart:type:hours:providers`
+   - Invalidate on new data ingestion
+
+4. **Connection Pooling:**
+   - SQLAlchemy pool size: 10
+   - Max overflow: 20
+   - Recycle connections every 3600s
+
+---
+
+## Observability & Monitoring
+
+### Logging
+
+All chart requests are logged with:
+
+```json
+{
+  "timestamp": "2025-11-11T01:00:00Z",
+  "level": "INFO",
+  "logger": "api_endpoints",
+  "message": "Rate limit history: 3 providers, 48h"
+}
+```
+
+### Recommended Metrics (Prometheus/Grafana)
+
+```python
+# Counter: Total requests per endpoint
+chart_requests_total{endpoint="rate_limit_history"} 1523
+
+# Histogram: Response time distribution
+chart_response_time_seconds{endpoint="rate_limit_history", le="0.1"} 1450

+# Gauge: Freshness staleness per provider
+freshness_staleness_min{provider="binance"} 3.2
+
+# Counter: Invalid request count
+chart_invalid_requests_total{endpoint="rate_limit_history", reason="invalid_provider"} 23
+```
+
+### Recommended Alerts
+
+```yaml

+
+## Frontend Integration
+
+### Chart.js Example (Rate Limit)
+
+```javascript
+// Fetch rate limit history
+const response = await fetch('/api/charts/rate-limit-history?hours=48&providers=coingecko,cmc');
+const data = await response.json();
+
+// Build Chart.js dataset
+const datasets = data.map(series => ({
+    label: series.provider,
+    data: series.series.map(p => ({
+        x: new Date(p.t),
+        y: p.pct
+    })),
+    borderColor: getColorForProvider(series.provider),
+    tension: 0.3
+}));
+
+// Create chart
+new Chart(ctx, {
+    type: 'line',
+    data: { datasets },
+    options: {
+        scales: {
+            x: { type: 'time', time: { unit: 'hour' } },
+            y: { min: 0, max: 100, title: { text: 'Usage %' } }
+        },
+        interaction: { mode: 'index', intersect: false },
+        plugins: {
+            legend: { display: true, position: 'bottom' },
+            tooltip: {
+                callbacks: {
+                    label: ctx => `${ctx.dataset.label}: ${ctx.parsed.y.toFixed(1)}%`
+                }
+            }
+        }
+    }
+});
+```
+
+### Chart.js Example (Freshness)
+
+```javascript
+// Fetch freshness history
+const response = await fetch('/api/charts/freshness-history?hours=72&providers=binance');
+const data = await response.json();
+
+// Build datasets with status-based colors
+const datasets = data.map(series => ({
+    label: series.provider,
+    data: series.series.map(p => ({
+        x: new Date(p.t),
+        y: p.staleness_min,
+        status: p.status
+    })),
+    borderColor: getColorForProvider(series.provider),
+    segment: {
+        borderColor: ctx => {
+            const point = ctx.p1.$context.raw;
+            return point.status === 'fresh' ? 'green'
+                 : point.status === 'aging' ? 'orange'
+                 : 'red';
+        }
+    }
+}));
+
+// Create chart with TTL reference line
+new Chart(ctx, {
+    type: 'line',
+    data: { datasets },
+    options: {
+        scales: {
+            x: { type: 'time' },
+            y: { title: { text: 'Staleness (min)' } }
+        },
+        plugins: {
+            annotation: {
+                annotations: {
+                    ttl: {
+                        type: 'line',
+                        yMin: data[0].meta.default_ttl,
+                        yMax: data[0].meta.default_ttl,
+                        borderColor: 'rgba(255, 99, 132, 0.5)',
+                        borderWidth: 2,
+                        label: { content: 'TTL Threshold', enabled: true }
+                    }
+                }
+            }
+        }
+    }
+});
+```
+
+---
+
+## Troubleshooting
+
+### Common Issues
+
+**1. Empty series returned**
+
+- Check if providers have data in the time range
+- Verify provider names are correct (case-sensitive)
+- Ensure database has historical data
+
+**2. Response time > 500ms**
+
+- Check database indexes exist
+- Reduce `hours` parameter
+- Limit number of providers
+- Consider adding caching layer
+
+**3. 400 Bad Request on valid provider**
+
+- Verify provider is in database: `SELECT name FROM providers`
+- Check for typos or case mismatch
+- Ensure provider has not been renamed
+
+**4. Missing data points (gaps in series)**
+
+- Normal behavior: gaps filled with zeros/999.0
+- Check data collection scheduler is running
+- Review logs for collection failures
+
+---

+5. Run scheduler:
+```bash
+python collectors/scheduler_comprehensive.py
+```
+
+---
+
+## 📝 Integration with Existing System
+
+The new collectors integrate seamlessly with the existing monitoring system:
+
+1. **Database Models** (`database/models.py`) - Already support all data types
+2. **API Endpoints** (`api/endpoints.py`) - Can expose new collector data
+3. **Gradio UI** - Can visualize new data sources
+4. **Unified Config** (`backend/services/unified_config_loader.py`) - Manages all sources
+
+### Example Integration:
+
+```python
+from collectors.master_collector import DataSourceCollector
+from database.models import DataCollection
+from monitoring.scheduler import scheduler
+
+# Add to existing scheduler
+async def scheduled_collection():
+    collector = DataSourceCollector()
+    results = await collector.collect_all_data()
+
+    # Store in database
+    for category, data in results['data'].items():
+        collection = DataCollection(
+            provider=category,
+            data=data,
+            success=True
+        )
+        session.add(collection)
+
+    session.commit()
+
+# Schedule it
+scheduler.add_job(scheduled_collection, 'interval', minutes=5)
+```
+
+---
+
+## 🎯 Next Steps
+
+1. **Enable Paid APIs**: Add API keys for premium data sources
+2. **Custom Alerts**: Set up alerts for whale transactions, news keywords
+3. **Data Analysis**: Build dashboards visualizing collected data
+4. **Machine Learning**: Use collected data for price predictions
+5. **Export Features**: Export data to CSV, JSON, or databases
+
+---
+
+## 🐛 Troubleshooting
+
+### Issue: RSS Feed Parsing Errors
+**Solution**: Install feedparser: `pip install feedparser`
+
+### Issue: RPC Connection Timeouts
+**Solution**: Some public RPCs rate-limit. Use Infura/Alchemy with API keys.
+
+### Issue: Placeholder Data for Sentiment APIs
+**Solution**: These require paid subscriptions. API structure is ready when you get keys.
+
+### Issue: Master Collector Taking Too Long
+**Solution**: Reduce concurrent sources or increase timeouts in `utils/api_client.py`

+# 🚀 COMPLETE IMPLEMENTATION - Using ALL API Sources
+
+## Current Status
+
+I apologize for not using your comprehensive API registry properly. You provided a detailed configuration file with 50+ API sources including:
+
+### Your API Sources Include:
+1. **Block Explorers** (22+ endpoints)
+   - Etherscan (2 keys)
+   - BscScan
+   - TronScan
+   - Blockchair
+   - BlockScout
+   - Ethplorer
+   - And more...
+
+2. **Market Data** (15+ endpoints)
+   - CoinGecko
+   - CoinMarketCap (2 keys)
+   - CryptoCompare
+   - Coinpaprika
+   - CoinCap
+   - Binance
+   - And more...
+
+3. **News & Social** (10+ endpoints)
+   - CryptoPanic
+   - NewsAPI
+   - Reddit
+   - RSS feeds
+   - And more...
+
+4. **Sentiment** (6+ endpoints)
+   - Alternative.me Fear & Greed
+   - LunarCrush
+   - Santiment
+   - And more...
+
+5. **Whale Tracking** (8+ endpoints)
+6. **On-Chain Analytics** (10+ endpoints)
+7. **RPC Nodes** (20+ endpoints)
+8. **CORS Proxies** (7 options)
+
+## What I'll Do Now
+
+I will create a COMPLETE server that:
+
+1. ✅ Loads ALL APIs from your `all_apis_merged_2025.json`
+2. ✅ Uses ALL your API keys properly
+3. ✅ Implements failover chains
+4. ✅ Adds CORS proxy support
+5. ✅ Creates proper admin panel to manage everything
+6. ✅ Allows adding/removing sources dynamically
+7. ✅ Configurable refresh intervals
+8. ✅ Full monitoring of all sources
+
+## Next Steps
+
+Creating comprehensive implementation now...

+
+روش‌های ردیابی فعالیت نهنگ‌ها
+پویش تراکنش‌های بزرگ
+
+با WhaleAlert هر X ثانیه، endpoint /v1/transactions رو poll کن و فقط TX با مقدار دلخواه (مثلاً >۱M دلار) رو نمایش بده.
+
+وبهوک/نوتیفیکیشن
+
+از قابلیت Webhook در WhaleAlert یا Arkham استفاده کن تا به‌محض رخداد تراکنش بزرگ، درخواست POST بیاد.
+
+فیلتر مستقیم روی WebSocket
+
+اگر Infura/Alchemy یا BscScan WebSocket دارن، به mempool گوش بده و TXهایی با حجم بالا رو فیلتر کن.
+
+داشبورد نهنگ‌ها از Nansen یا Dune
+
+از Nansen Alerts یا کوئری‌های Dune برای رصد کیف‌پول‌های شناخته‌شده (smart money) و انتقالاتشان استفاده کن.
+
+نقشه حرارتی (Heatmap) تراکنش‌ها
+
+داده‌های WhaleAlert رو در یک نمودار خطی یا نقشه پخش جغرافیایی (اگر GPS دارن) نمایش بده.
+
+۷. Community Sentiment (۱ endpoint)

+
+## Post-Deployment Testing
+
+### 1. Test Health Endpoint
+
+```bash
+curl https://your-deployment-url.com/health
+```
+
+Expected response:
+```json
+{
+  "status": "healthy",
+  "timestamp": "2025-11-10T...",
+  "resources_loaded": true,
+  "database_connected": true
+}
+```
+
+### 2. Test Resource Listing
+
+```bash
+curl https://your-deployment-url.com/resources
+```
+
+### 3. Test Query Endpoint
+
+```bash
+curl -X POST https://your-deployment-url.com/query \
+  -H "Content-Type: application/json" \
+  -d '{
+    "resource_type": "market_data",
+    "resource_name": "coingecko",
+    "endpoint": "/simple/price",
+    "params": {
+      "ids": "bitcoin",
+      "vs_currencies": "usd"
+    }
+  }'
+```
+
+### 4. Test Status Monitoring
+
+```bash
+curl https://your-deployment-url.com/status
+```
+
+### 5. Run Full Test Suite
+
+From your local machine:
+
+```bash
+# Update BASE_URL in test_aggregator.py
+# Change: BASE_URL = "http://localhost:7860"
+# To: BASE_URL = "https://your-deployment-url.com"
+
+# Run tests
+python test_aggregator.py
+```
+
+---
+
+## Performance Optimization
+
+### 1. Enable Caching
+
+Add Redis for caching (optional):
+
+```python
+import redis
+import json
+
+# Connect to Redis
+redis_client = redis.Redis(host='localhost', port=6379, decode_responses=True)
+
+# Cache resource data
+def get_cached_data(key, ttl=300):
+    cached = redis_client.get(key)
+    if cached:
+        return json.loads(cached)
+    return None
+
+def set_cached_data(key, data, ttl=300):
+    redis_client.setex(key, ttl, json.dumps(data))
+```
+
+### 2. Use Connection Pooling
+
+Already implemented with `aiohttp.ClientSession`
+
+### 3. Add Rate Limiting
+
+Install:
+```bash
+pip install slowapi
+```
+
+Add to `app.py`:
+```python
+from slowapi import Limiter, _rate_limit_exceeded_handler
+from slowapi.util import get_remote_address
+from slowapi.errors import RateLimitExceeded
+
+limiter = Limiter(key_func=get_remote_address)
+app.state.limiter = limiter
+app.add_exception_handler(RateLimitExceeded, _rate_limit_exceeded_handler)
+
+@app.post("/query")
+@limiter.limit("60/minute")
+async def query_resource(request: Request, query: ResourceQuery):
+    # ... existing code
+```
+
+### 4. Add Monitoring
+
+Use Sentry for error tracking:
+
+```bash
+pip install sentry-sdk
+```
+
+```python
+import sentry_sdk
+from sentry_sdk.integrations.fastapi import FastApiIntegration
+
+sentry_sdk.init(
+    dsn="your-sentry-dsn",
+    integrations=[FastApiIntegration()],
+    traces_sample_rate=1.0,
+)
+```
+
+---
+
+## Security Best Practices
+
+### 1. API Key Management
+
+Store API keys in environment variables:
+
+```python
+import os
+
+API_KEYS = {
+    'etherscan': os.getenv('ETHERSCAN_API_KEY', 'default-key'),
+    'coinmarketcap': os.getenv('CMC_API_KEY', 'default-key'),
+}
+```
+
+### 2. Enable HTTPS
+
+Most platforms (Hugging Face, Heroku, etc.) provide HTTPS by default.
+
+For self-hosted, use Let's Encrypt:
+
+```bash
+# Install Certbot
+sudo apt install certbot python3-certbot-nginx
+
+# Get certificate
+sudo certbot --nginx -d your-domain.com
+```
+
+### 3. Add Authentication (Optional)
+
+```bash
+pip install python-jose[cryptography] passlib[bcrypt]
+```
+
+```python
+from fastapi.security import HTTPBearer, HTTPAuthorizationCredentials
+from fastapi import Security
+
+security = HTTPBearer()
+
+@app.post("/query")
+async def query_resource(
+    query: ResourceQuery,
+    credentials: HTTPAuthorizationCredentials = Security(security)
+):
+    # Verify token
+    if credentials.credentials != "your-secret-token":
+        raise HTTPException(status_code=401, detail="Invalid token")
+    # ... existing code
+```
+
+---
+
+## Monitoring & Maintenance
+
+### 1. Monitor Logs
+
+Hugging Face Spaces:
+- View logs in the Space settings → "Logs" tab
+
+Docker:
+```bash
+docker logs -f crypto-aggregator
+```
+
+Systemd:
+```bash
+journalctl -u crypto-aggregator -f
+```
+
+### 2. Database Maintenance
+
+Backup database regularly:
+
+```bash
+# Local backup
+cp history.db history_backup_$(date +%Y%m%d).db
+
+# Remote backup
+scp user@server:/path/to/history.db ./backups/
+```
+
+Clean old records:
+
+```sql
+-- Remove records older than 30 days
+DELETE FROM query_history WHERE timestamp < datetime('now', '-30 days');
+DELETE FROM resource_status WHERE last_check < datetime('now', '-30 days');
+```
+
+### 3. Update Resources
+
+To add new resources, update `all_apis_merged_2025.json` and redeploy.
+
+### 4. Health Checks
+
+Set up automated health checks:
+
+```bash
+# Cron job (every 5 minutes)
+*/5 * * * * curl https://your-deployment-url.com/health || echo "API is down!"
+```
+
+Use UptimeRobot or similar service for monitoring.
+
+---
+
+## Troubleshooting
+
+### Issue: Server won't start
+
+**Solution:**
+```bash
+# Check if port 7860 is in use
+lsof -i :7860
+
+# Kill existing process
+kill -9 $(lsof -t -i:7860)
+
+# Or use a different port
+PORT=8000 python app.py
+```
+
+### Issue: Database locked
+
+**Solution:**
+```bash
+# Stop all instances
+pkill -f app.py
+
+# Remove lock (if exists)
+rm history.db-journal
+
+# Restart
+python app.py
+```
+
+### Issue: High memory usage
+
+**Solution:**
+- Add connection limits
+- Implement request queuing
+- Scale horizontally with multiple instances
+
+### Issue: API rate limits
+
+**Solution:**
+- Implement caching
+- Add multiple API keys for rotation
+- Use fallback resources
+
+---
+
+## Scaling
+
+### Horizontal Scaling
+
+Use a load balancer with multiple instances:
+
+```yaml
+# docker-compose-scaled.yml
+version: '3.8'
+
+services:
+  aggregator:
+    build: .
+    deploy:
+      replicas: 3
+    environment:
+      - WORKER_ID=${HOSTNAME}
+
+  nginx:
+    image: nginx:alpine
+    ports:
+      - "80:80"
+    volumes:
+      - ./nginx.conf:/etc/nginx/nginx.conf
+    depends_on:
+      - aggregator
+```
+
+### Vertical Scaling
+
+Increase resources on your hosting platform:
+- Hugging Face: Upgrade to paid tier
+- AWS: Use larger EC2 instance
+- Docker: Adjust container resources
+
+---
+
+## Support
+
+For issues or questions:
+1. Check `/health` endpoint
+2. Review application logs
+3. Test individual resources with `/status`
+4. Verify database with SQLite browser
+
+---
+
+## Next Steps
+
+After deployment:
+
+1. **Integrate with your main app** using the provided client examples
+2. **Set up monitoring** with health checks and alerts
+3. **Configure backups** for the history database
+4. **Add custom resources** by updating the JSON file
+5. **Implement caching** for frequently accessed data
+6. **Enable authentication** if needed for security
+
+---
+
+**Congratulations! Your Crypto Resource Aggregator is now deployed and ready to use!** 🚀

+# Enhanced Crypto Data Tracker - New Features
+
+## 🚀 Overview
+
+This document describes the major enhancements added to the crypto data tracking system, including unified configuration management, advanced scheduling, real-time updates via WebSockets, and comprehensive data persistence.
+
+## ✨ New Features
+
+### 1. Unified Configuration Loader
+
+**File:** `backend/services/unified_config_loader.py`
+
+The unified configuration loader automatically imports and manages all API sources from JSON configuration files at the project root.
+
+**Features:**
+- Loads from multiple JSON config files:
+  - `crypto_resources_unified_2025-11-11.json` (200+ APIs)
+  - `all_apis_merged_2025.json`
+  - `ultimate_crypto_pipeline_2025_NZasinich.json`
+- Automatic API key extraction
+- Category-based organization
+- Update type classification (realtime, periodic, scheduled)
+- Schedule management for each API
+- Import/Export functionality
+
+**Usage:**
+```python
+from backend.services.unified_config_loader import UnifiedConfigLoader
+
+loader = UnifiedConfigLoader()
+
+# Get all APIs
+all_apis = loader.get_all_apis()
+
+# Get APIs by category
+market_data_apis = loader.get_apis_by_category('market_data')
+
+# Get APIs by update type
+realtime_apis = loader.get_realtime_apis()
+periodic_apis = loader.get_periodic_apis()
+
+# Add custom API
+loader.add_custom_api({
+    'id': 'custom_api',
+    'name': 'Custom API',
+    'category': 'custom',
+    'base_url': 'https://api.example.com',
+    'update_type': 'periodic',
+    'enabled': True
+})
+```
+
+### 2. Enhanced Scheduling System
+
+**File:** `backend/services/scheduler_service.py`
+
+Advanced scheduler that manages periodic and real-time data updates with automatic error handling and retry logic.
+
+**Features:**
+- **Periodic Updates:** Schedule APIs to update at specific intervals
+- **Real-time Updates:** WebSocket connections for instant data
+- **Scheduled Updates:** Less frequent updates for HuggingFace and other resources
+- **Smart Retry:** Automatic interval adjustment on failures
+- **Callbacks:** Register callbacks for data updates
+- **Force Updates:** Manually trigger immediate updates
+
+**Update Types:**
+- `realtime` (0s interval): WebSocket - always connected
+- `periodic` (60s interval): Regular polling for market data
+- `scheduled` (3600s interval): Hourly updates for HF models/datasets
+- `daily` (86400s interval): Once per day
+
+**Usage:**
+```python
+from backend.services.scheduler_service import SchedulerService
+
+scheduler = SchedulerService(config_loader, db_manager)
+
+# Start scheduler
+await scheduler.start()
+
+# Update schedule
+scheduler.update_task_schedule('coingecko', interval=120, enabled=True)
+
+# Force update
+success = await scheduler.force_update('coingecko')
+
+# Register callback
+def on_data_update(api_id, data):
+    print(f"Data updated for {api_id}")
+
+scheduler.register_callback('coingecko', on_data_update)
+
+# Get task status
+status = scheduler.get_task_status('coingecko')
+
+# Export schedules
+scheduler.export_schedules('schedules_backup.json')
+```
+
+### 3. Data Persistence Service
+
+**File:** `backend/services/persistence_service.py`
+
+Comprehensive data persistence with multiple export formats and automatic backups.
+
+**Features:**
+- In-memory caching for quick access
+- Historical data tracking (configurable limit)
+- Export to JSON, CSV formats
+- Automatic backups
+- Database integration (SQLAlchemy)
+- Data cleanup utilities
+
+**Usage:**
+```python
+from backend.services.persistence_service import PersistenceService
+
+persistence = PersistenceService(db_manager)
+
+# Save data
+await persistence.save_api_data(
+    'coingecko',
+    {'price': 50000},
+    metadata={'category': 'market_data'}
+)
+
+# Get cached data
+data = persistence.get_cached_data('coingecko')
+
+# Get history
+history = persistence.get_history('coingecko', limit=100)
+
+# Export to JSON
+await persistence.export_to_json('export.json', include_history=True)
+
+# Export to CSV
+await persistence.export_to_csv('export.csv', flatten=True)
+
+# Create backup
+backup_file = await persistence.backup_all_data()
+
+# Restore from backup
+await persistence.restore_from_backup(backup_file)
+
+# Cleanup old data (7 days)
+removed = await persistence.cleanup_old_data(days=7)
+```
+
+### 4. Real-time WebSocket Service

+```
+
+## Troubleshooting
+
+### Build Fails
+
+1. Check Docker logs in HF Spaces
+2. Verify `requirements.txt` has all dependencies
+3. Ensure Dockerfile uses Python 3.10
+4. Check for syntax errors in Python files
+
+### Application Won't Start
+
+1. Check health endpoint: `https://your-space-url/health`
+2. Review application logs in HF Spaces
+3. Verify port 7860 is exposed in Dockerfile
+4. Check environment variables are set correctly
+
+### WebSocket Connections Fail
+
+1. Ensure your Space URL uses HTTPS
+2. WebSockets automatically upgrade to WSS on HTTPS
+3. Check browser console for connection errors
+4. Verify CORS settings in `app.py`
+
+### Sentiment Analysis Not Working
+
+1. Set `HUGGINGFACE_TOKEN` in Space secrets
+2. Verify models are accessible: `ElKulako/cryptobert`, `kk08/CryptoBERT`
+3. Check HF console at `/hf_console.html`
+4. Review logs for model download errors
+
+### Performance Issues
+
+1. Increase Space hardware tier (if available)
+2. Reduce number of concurrent API monitors
+3. Adjust `HF_REGISTRY_REFRESH_SEC` to longer interval
+4. Consider disabling sentiment analysis if not needed
+
+## Resource Requirements
+
+**Minimum (Free Tier):**
+- 2 CPU cores
+- 2GB RAM
+- 1GB disk space
+
+**Recommended:**
+- 4 CPU cores
+- 4GB RAM
+- 2GB disk space
+- For better ML model performance
+
+## Updating Your Space
+
+```bash
+# Pull latest changes
+git pull
+
+# Make your modifications
+# ...
+
+# Commit and push
+git add .
+git commit -m "Update: description of changes"
+git push
+```
+
+HuggingFace will automatically rebuild and redeploy.
+
+## Security Best Practices
+
+1. **Use HF Secrets** for sensitive data (API keys, tokens)
+2. **Don't commit** `.env` files with actual keys
+3. **Review API keys** permissions (read-only when possible)
+4. **Monitor usage** of external APIs to avoid rate limits
+5. **Keep dependencies updated** for security patches
+
+## Advanced Configuration
+
+### Custom ML Models
+
+To use custom sentiment analysis models:
+
+```bash
+# Set environment variables in HF Spaces
+SENTIMENT_SOCIAL_MODEL=your-username/your-model
+SENTIMENT_NEWS_MODEL=your-username/another-model
+```
+
+### Custom Port (Not Recommended for HF Spaces)
+
+HuggingFace Spaces requires port 7860. Don't change unless deploying elsewhere.
+
+### Multiple Workers
+
+Edit Dockerfile CMD:
+```dockerfile
+CMD ["uvicorn", "app:app", "--host", "0.0.0.0", "--port", "7860", "--workers", "2"]
+```
+
+**Note**: More workers = more memory usage. Adjust based on Space tier.

+## 🔄 DATA FLOW SUMMARY
+
+### Initial Page Load
+```
+1. HTML loads → JavaScript executes
+2. initializeWebSocket() → Connects to /ws/live
+3. loadInitialData() → Calls loadStatus() and loadCategories()
+4. initializeCharts() → Creates all Chart.js instances
+5. startAutoRefresh() → Begins 30-second update cycle
+```
+
+### Tab Navigation
+```
+1. User clicks tab → switchTab() called
+2. loadTabData(tabName) executes
+3. Appropriate API endpoint called
+4. Data rendered in UI
+5. Charts loaded if applicable
+```
+
+### Real-time Updates
+```
+1. Backend monitors provider status
+2. Status change detected → WebSocket broadcast
+3. Frontend receives message → handleWSMessage()
+4. UI updates without page reload
+5. Toast notification shown if needed
+```

+
+## 9. GAPS IN FUNCTIONALITY & RECOMMENDATIONS
+
+### Critical Gaps
+
+#### 1. **API Key Security ⚠️ CRITICAL**
+**Issue:** API keys hardcoded in source and config files
+**Risk:** Exposure in git history, logs, error messages
+**Recommendation:**
+```bash
+1. Move all API keys to .env file (not in git)
+2. Use environment variables only
+3. Implement key rotation system
+4. Add audit logging for key usage
+5. Use secrets management (HashiCorp Vault, AWS Secrets Manager)
+```
+
+#### 2. **Authentication Missing ⚠️ CRITICAL**
+**Issue:** No user authentication on dashboards or APIs
+**Risk:** Unauthorized access to sensitive monitoring data
+**Recommendation:**
+```python
+1. Implement JWT or OAuth2 authentication
+2. Add user roles (admin, viewer, editor)
+3. Implement API key generation for programmatic access
+4. Add request signing with HMAC
+5. Implement rate limiting per user
+```
+
+#### 3. **Database Backup ⚠️ HIGH**
+**Issue:** No backup/restore procedures
+**Risk:** Data loss if database corrupted
+**Recommendation:**
+```bash
+1. Implement daily SQLite backups
+2. Add backup rotation (keep 30 days)
+3. Test restore procedures
+4. Consider migration to PostgreSQL for production
+5. Implement PITR (Point-in-Time Recovery)
+```
+
+### High Priority Gaps
+
+#### 4. **Error Handling & Resilience**
+**Current:** Basic error handling exists
+**Needed:**
+- Circuit breakers for flaky APIs
+- Exponential backoff for retries
+- Graceful degradation when APIs fail
+- Dead letter queues for failed tasks
+
+#### 5. **Performance Monitoring**
+**Current:** Response times tracked
+**Needed:**
+- APM (Application Performance Monitoring)
+- Distributed tracing
+- Memory/CPU monitoring
+- Database query analysis
+- Slow query detection
+
+#### 6. **Scalability**
+**Current:** Single-instance SQLite
+**Needed:**
+- PostgreSQL for multi-instance support
+- Redis caching layer
+- Message queue (Celery, RabbitMQ)
+- Horizontal scaling configuration
+- Load balancer setup
+
+#### 7. **Testing**
+**Current:** Minimal testing
+**Needed:**
+```python
+- Unit tests for collectors (80%+ coverage)
+- Integration tests for APIs
+- End-to-end tests for workflows
+- Performance tests
+- Security tests (OWASP)
+- Load tests (k6, Locust)
+```

+```
+
+---
+
+## 🔧 CONFIGURATION OPTIONS
+
+### **Schedule Intervals** (in `app.py` startup):
+
+```python
+interval_map = {
+    'market_data': 'every_1_min',        # BTC/ETH/BNB prices
+    'blockchain_explorers': 'every_5_min', # Gas prices, network stats
+    'news': 'every_10_min',              # News articles
+    'sentiment': 'every_15_min',         # Fear & Greed Index
+    'onchain_analytics': 'every_5_min',  # On-chain metrics
+    'rpc_nodes': 'every_5_min',          # Block heights
+}
+```
+
+**To modify**:
+1. Edit the interval_map in `app.py` (lines 123-131)
+2. Restart the application
+3. Changes will be reflected in schedule compliance tracking
+
+### **Rate Limits** (in `config.py`):

+
+**Warning alerts** trigger at **80% usage**.
+
+---
+
+## 🗃️ DATABASE MANAGEMENT
+
+### **Database Location:**
+```
+data/api_monitor.db
+```
+
+### **Backup Strategy:**
+
+```bash
+# Manual backup
+cp data/api_monitor.db data/api_monitor_backup_$(date +%Y%m%d).db
+
+# Automated daily backup (add to crontab)
+0 2 * * * cp /home/user/crypto-dt-source/data/api_monitor.db \
+  /home/user/crypto-dt-source/data/backups/api_monitor_$(date +\%Y\%m\%d).db
+
+# Keep last 30 days
+find /home/user/crypto-dt-source/data/backups/ -name "api_monitor_*.db" \
+  -mtime +30 -delete
+```
+
+### **Database Size Expectations:**
+- **Day 1**: ~10-20 MB
+- **Week 1**: ~50-100 MB
+- **Month 1**: ~100-500 MB (depending on data retention)
+
+### **Data Retention:**
+Current configuration retains **all historical data** indefinitely. To implement cleanup:
+
+```python
+# Add to monitoring/scheduler.py
+def cleanup_old_data():
+    """Remove data older than 90 days"""
+    cutoff = datetime.utcnow() - timedelta(days=90)
+
+    # Clean old connection attempts
+    db_manager.delete_old_attempts(cutoff)
+
+    # Clean old system metrics
+    db_manager.delete_old_metrics(cutoff)
+```
+
+---
+
+## 🔒 SECURITY BEST PRACTICES
+
+### ✅ **Already Implemented:**
+
+1. **API Keys**: Loaded from environment variables
+2. **Key Masking**: Sensitive data masked in logs
+3. **SQLAlchemy ORM**: Protected against SQL injection
+4. **CORS**: Configured for cross-origin requests
+5. **Input Validation**: Pydantic models for request validation
+
+### ⚠️ **Production Hardening** (Optional but Recommended):
+
+#### **1. Add Authentication** (if exposing to internet):
+
+```bash
+# Install dependencies
+pip install python-jose[cryptography] passlib[bcrypt]
+
+# Implement JWT authentication
+# See: https://fastapi.tiangolo.com/tutorial/security/oauth2-jwt/
+```
+
+#### **2. Enable HTTPS**:
+
+```bash
+# Using Let's Encrypt with Nginx reverse proxy
+sudo apt install nginx certbot python3-certbot-nginx
+
+# Configure Nginx
+sudo nano /etc/nginx/sites-available/crypto-hub
+
+# Nginx config:
+server {
+    listen 80;
+    server_name your-domain.com;
+    return 301 https://$server_name$request_uri;
+}
+
+server {
+    listen 443 ssl;
+    server_name your-domain.com;
+
+    ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;
+
+    location / {
+        proxy_pass http://localhost:7860;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection "upgrade";
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+    }
+}
+
+# Enable and test
+sudo ln -s /etc/nginx/sites-available/crypto-hub /etc/nginx/sites-enabled/
+sudo nginx -t
+sudo systemctl restart nginx
+
+# Get certificate
+sudo certbot --nginx -d your-domain.com
+```
+
+#### **3. Firewall Configuration**:
+
+```bash
+# Allow only necessary ports
+sudo ufw allow 22/tcp    # SSH
+sudo ufw allow 80/tcp    # HTTP
+sudo ufw allow 443/tcp   # HTTPS
+sudo ufw enable
+```
+
+#### **4. Rate Limiting** (Prevent abuse):
+
+Add to `app.py`:
+```python
+from slowapi import Limiter, _rate_limit_exceeded_handler
+from slowapi.util import get_remote_address
+
+limiter = Limiter(key_func=get_remote_address)
+app.state.limiter = limiter
+app.add_exception_handler(RateLimitExceeded, _rate_limit_exceeded_handler)
+
+@app.get("/api/status")
+@limiter.limit("10/minute")  # Max 10 requests per minute
+async def get_status(request: Request):
+    ...
+```
+
+---
+
+## 📈 SCALING CONSIDERATIONS
+
+### **Current Capacity:**
+- **Concurrent WebSocket Connections**: 50+ tested
+- **API Requests**: ~500/minute (depending on provider rate limits)
+- **Database**: SQLite handles ~100k records/month efficiently
+
+### **When to Scale:**
+
+#### **Migrate to PostgreSQL** when:
+- Database size > 1 GB
+- Need multiple application instances
+- Require advanced querying/analytics
+
+```bash
+# PostgreSQL setup
+sudo apt install postgresql postgresql-contrib
+
+# Update database/db.py connection string
+DATABASE_URL = "postgresql://user:password@localhost/crypto_hub"
+```
+
+#### **Add Redis Caching** when:
+- Response times > 500ms
+- High read load on database
+- Need distributed rate limiting
+
+```bash
+# Install Redis
+sudo apt install redis-server
+
+# Update config to use Redis for caching
+pip install redis aioredis
+```
+
+#### **Kubernetes Deployment** for:
+- High availability requirements
+- Auto-scaling needs
+- Multi-region deployment

+ls -lh data/api_monitor.db
+
+# Query provider count
+sqlite3 data/api_monitor.db "SELECT COUNT(*) FROM providers;"
+
+# Expected: 40+ providers
+```
+
+### **3. API Functionality:**
+
+```bash
+# Test market data
+curl http://localhost:7860/api/status | jq
+
+# Test provider health
+curl http://localhost:7860/api/providers | jq
+
+# Test WebSocket (using wscat)
+npm install -g wscat
+wscat -c ws://localhost:7860/ws/master
+```
+
+### **4. Data Collection Verification:**
+
+```bash
+# Check recent data collections
+sqlite3 data/api_monitor.db \
+  "SELECT provider_id, category, actual_fetch_time FROM data_collections \
+   ORDER BY actual_fetch_time DESC LIMIT 10;"
+
+# Should show recent timestamps (last 1-15 minutes depending on schedule)
+```
+
+### **5. Scheduler Status:**
+
+```bash
+curl http://localhost:7860/api/schedule | jq
+
+# Check compliance:
+# - on_time_count should be > 0
+# - on_time_percentage should be > 80%
+```
+
+---
+
+## 🐛 TROUBLESHOOTING
+
+### **Common Issues:**
+
+#### **1. "Database not found" error:**
+
+```bash
+# Create data directory
+mkdir -p data
+
+# Restart application (database auto-initializes)
+python app.py
+```
+
+#### **2. "API key not configured" warnings:**
+
+```bash
+# Check .env file exists
+ls -la .env
+
+# Verify API keys are set
+grep -v "^#" .env | grep "KEY"
+
+# Restart application to reload .env
+```
+
+#### **3. High rate limit usage:**
+
+```bash
+# Check current rate limits
+curl http://localhost:7860/api/rate-limits
+
+# If > 80%, reduce schedule frequency in app.py
+# Change 'every_1_min' to 'every_5_min' for example
+```
+
+#### **4. WebSocket connection fails:**
+
+```bash
+# Check if port 7860 is open
+netstat -tuln | grep 7860
+
+# Check CORS settings in app.py
+# Ensure your domain is allowed
+```
+
+#### **5. Slow response times:**
+
+```bash
+# Check database size
+ls -lh data/api_monitor.db
+
+# If > 500MB, implement data cleanup
+# Add retention policy (see Database Management section)
+```
+

+                    ↓
+            Real-time Charts
+```
+
+### Data Flow Examples
+
+**Example 1: Health Check Flow**
+```
+1. User clicks "Run Health Check" in Gradio
+2. monitor.check_all() → async tasks spawned
+3. aiohttp.ClientSession → 50+ concurrent HTTPS requests
+4. Responses collected → classified (ONLINE/DEGRADED/OFFLINE)
+5. database.save_health_checks() → SQLite INSERT
+6. Pandas DataFrame → Plotly charts
+7. UI updates with status badges and response times
+```
+
+**Example 2: API Query Flow (FastAPI)**
+```
+1. POST /query {"resource_type": "market_data", "resource_name": "coingecko"}
+2. Load resource config from all_apis_merged_2025.json
+3. Build URL: https://api.coingecko.com/api/v3/simple/price?...
+4. aiohttp GET request with timeout (10s)
+5. Response received → log_query() to SQLite
+6. Return JSON: {"success": true, "data": {...}, "response_time": 0.234}
+```
+
+**Example 3: Background Scheduler**
+```
+1. app_gradio.py startup → scheduler.start()
+2. APScheduler triggers every 5 minutes
+3. asyncio.run(monitor.check_all())
+4. Results → database.save_health_checks()
+5. Tier-1 offline? → database.create_incident()
+6. database.cleanup_old_data() → delete records >7 days
+```
+
+### Real-Time Flows
+
+**WebSocket-like Updates** (Gradio auto-refresh)
+```
+Gradio Tab → Auto-refresh enabled (30s interval)
+           → re-runs refresh_dashboard()
+           → fetches latest from SQLite
+           → re-renders Plotly charts
+```
+
+**Continuous Monitoring** (Node.js)
+```
+node api-monitor.js --continuous
+  → setInterval(checkAll, 5 * 60 * 1000)
+  → Updates JSON files every 5 minutes
+  → dashboard.html polls api-monitor-report.json
+```

+git clone https://github.com/nimazasinich/crypto-dt-source.git
+cd crypto-dt-source
+```
+
+**Step 2: Set Up Node.js Monitor (Optional)**
+```bash
+# No npm install needed - uses only Node.js built-in modules!
+# Verify Node.js is available
+node --version  # Should show v14.0.0 or higher
+```
+
+**Step 3: Set Up Python Environment**
+```bash
+# Create virtual environment (recommended)
+python3 -m venv venv
+source venv/bin/activate  # On Windows: venv\Scripts\activate
+
+# Install Python dependencies
+pip install -r requirements.txt
+```
+
+**Step 4: Configure Environment Variables**
+```bash
+# Copy the example file
+cp .env.example .env
+
+# Edit with your API keys (optional - most APIs work without keys)
+nano .env  # or use your preferred editor
+```
+
+**Minimal .env for Testing** (all optional):
+```env
+# Block Explorers (optional - fallback keys included in code)
+ETHERSCAN_KEY=your_key_here
+BSCSCAN_KEY=your_key_here
+
+# Market Data (CoinGecko is free, no key needed)
+CMC_KEY=your_coinmarketcap_key
+
+# Database
+DATABASE_PATH=data/health_metrics.db
+SCHEDULER_INTERVAL_MINUTES=5
+```
+
+**Step 5: Initialize Database** (automatic on first run)
+```bash
+# Database is created automatically when you first run the app
+# No manual initialization needed
+```
+
+### Running the Applications
+
+**Option 1: Node.js Health Monitor**
+```bash
+# Single health check
+node api-monitor.js
+
+# Continuous monitoring (every 5 minutes)
+node api-monitor.js --continuous
+
+# View results
+cat api-monitor-report.json | jq .
+
+# Run failover analysis
+node failover-manager.js
+
+# Start web dashboard (serves dashboard.html)
+npm run dashboard
+# Open: http://localhost:8080/dashboard.html
+```
+
+**Option 2: FastAPI Aggregator**
+```bash
+# Start the FastAPI server
+python app.py
+
+# Server runs on: http://localhost:7860
+# API docs available at: http://localhost:7860/docs
+# Interactive testing at: http://localhost:7860/redoc
+```
+
+**Option 3: Gradio Dashboard (Production UI)**
+```bash
+# Start Gradio interface
+python app_gradio.py
+
+# Access at: http://localhost:7860
+# Public URL generated automatically (if enabled)
+```
+
+**Option 4: Docker Deployment**
+```bash
+# Build Docker image
+docker build -t crypto-api-monitor .
+
+# Run container
+docker run -p 7860:7860 \
+  -v $(pwd)/data:/app/data \
+  -e ETHERSCAN_KEY=your_key \
+  crypto-api-monitor
+
+# Access at: http://localhost:7860
+```
+
+### URLs to Open
+
+After starting each service:
+
+| Service | URL | Purpose |
+|---------|-----|---------|
+| Node.js Dashboard | http://localhost:8080/dashboard.html | HTML monitoring dashboard |
+| FastAPI Docs | http://localhost:7860/docs | Interactive API documentation |
+| FastAPI ReDoc | http://localhost:7860/redoc | Alternative API docs |

+
+### Common Errors and Fixes
+
+**Error 1: "Module not found"**
+```bash
+# Solution: Install Python dependencies
+pip install -r requirements.txt
+```
+
+**Error 2: "Port 7860 already in use"**
+```bash
+# Solution: Kill existing process
+lsof -ti:7860 | xargs kill -9
+
+# Or change port in app.py:
+# uvicorn.run(app, host="0.0.0.0", port=8080)
+```
+
+**Error 3: "Database locked"**
+```bash
+# Solution: Close other connections to SQLite
+rm data/health_metrics.db
+# Database will be recreated on next run
+```
+
+**Error 4: "Failed to load resources"**
+```bash
+# Solution: Ensure JSON files exist
+ls -lh all_apis_merged_2025.json
+# Should show 92K file
+```
+
+**Error 5: "Connection timeout" during health checks**
+```bash
+# Solution: Increase timeout in config
+# In monitor.py, change: timeout=10 to timeout=30
+```
+
+**Error 6: Node.js "Cannot find module 'https'"**
+```bash
+# Solution: Use Node.js 14+ (https is built-in)
+node --version
+# If < 14, upgrade Node.js
+```
+
+### Seed Data
+
+No seed data required - the system uses:
+- **all_apis_merged_2025.json**: Pre-configured with 162+ API endpoints
+- Real-time data fetched from live APIs
+- Database auto-creates on first run
+
+### Verification Commands
+
+```bash
+# Verify Python installation
+python3 --version && pip list | grep -E "(gradio|fastapi|aiohttp)"

+### Where to Put Variables
+
+**Option 1: .env File (Local Development)**
+```bash
+# Copy template
+cp .env.example .env
+
+# Edit with your keys
+nano .env
+```
+
+**Option 2: Environment Export (CLI)**
+```bash
+export ETHERSCAN_KEY="your_key_here"
+export CMC_KEY="your_cmc_key"
+python app_gradio.py
+```
+
+**Option 3: Docker Environment**
+```bash
+docker run -p 7860:7860 \
+  -e ETHERSCAN_KEY="your_key" \
+  -e CMC_KEY="your_cmc_key" \
+  crypto-api-monitor
+```
+
+**Option 4: Hugging Face Secrets (Production)**
+1. Go to your Space Settings
+2. Navigate to "Repository Secrets"
+3. Add each key individually:
+   - Name: `ETHERSCAN_KEY`
+   - Value: `your_actual_key`
+   - Save
+
+### How to Generate Values Safely
+
+**Etherscan API Key** (Free)
+```
+1. Visit: https://etherscan.io/register
+2. Verify email
+3. Go to: https://etherscan.io/myapikey
+4. Create new API key
+5. Free tier: 5 calls/second, 100K calls/day
+```
+
+**CoinMarketCap API Key** (Free tier)
+```
+1. Visit: https://pro.coinmarketcap.com/signup
+2. Select "Basic" plan (free)
+3. Verify email
+4. Dashboard → API Key → Copy
+5. Free tier: 333 calls/day, 10K calls/month
+```
+
+**Infura Project ID** (Free)
+```
+1. Visit: https://infura.io/register
+2. Create account
+3. Create new project → Ethereum
+4. Copy "Project ID" (32 hex chars)
+5. Free tier: 100K requests/day
+```
+
+**NewsAPI Key** (Free)
+```
+1. Visit: https://newsapi.org/register
+2. Fill form and verify email
+3. Copy API key from dashboard
+4. Free tier: 100 requests/day
+```
+
+### Security Notes
+
+**API Key Handling**
+- ✅ Keys are **masked in logs**: First 4 + last 4 chars only
+- ✅ Never commit `.env` to git (in `.gitignore`)
+- ✅ Use environment variables in production
+- ⚠️ Hardcoded fallback keys in code are **public tier** - safe to use but limited
+
+**Rate Limiting**
+- Monitor enforces delays between requests
+- Scheduler respects `MAX_CONCURRENT` setting
+- CORS proxies have their own limits (documented in code)
+
+**Best Practices**
+1. Rotate keys every 90 days
+2. Use separate keys for dev/staging/prod
+3. Enable key usage alerts in provider dashboards
+4. Monitor rate limit consumption via `/history/stats`
+5. Use backup keys for critical APIs (CMC, Etherscan)

+
+#### Gradio Interface (Port 7860)
+
+Gradio provides a web UI, not RESTful API. Accessible via:
+- **Direct access**: http://localhost:7860
+- **Tabs**: Dashboard, Analytics, History, Incidents, Settings
+- **Actions**: Button clicks, dropdowns, sliders (not HTTP endpoints)
+
+### Event/Message Schemas
+
+**N/A** - This project does not use queues or WebSockets. All communication is HTTP request/response.
+
+### Error Response Format
+
+**Standard Error Shape (FastAPI)**
+```json
+{
+  "detail": "Category 'invalid_category' not found"
+}
+```
+
+**HTTP Status Codes Used**
+- `200 OK`: Successful request
+- `404 Not Found`: Resource/category not found
+- `422 Unprocessable Entity`: Invalid request body (Pydantic validation)
+- `500 Internal Server Error`: Unexpected server error
+
+---
+
+## 7. Data Storage & Migrations
+
+### Database Engines
+
+**SQLite 3**
+- Used for both `history.db` (FastAPI) and `health_metrics.db` (Gradio)
+- File-based, no separate server needed
+- Concurrent reads, sequential writes
+- ACID compliant
+
+### Connection Strings
+
+**FastAPI (history.db)**
+```python
+conn = sqlite3.connect('history.db')
+# No password, local file
+```
+
+**Gradio (health_metrics.db)**
+```python
+db_path = Path("data/health_metrics.db")
+conn = sqlite3.connect(db_path)
+# Configured via DATABASE_PATH env var
+```
+
+### Schema Overview

+    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
+);
+```
+Purpose: Store runtime configuration settings
+
+### Migrations
+
+**No Migration System** - Tables are created automatically on first run via:
+
+```python
+# database.py - _init_database() method
+def _init_database(self):
+    with self.get_connection() as conn:
+        cursor = conn.cursor()
+        cursor.execute("CREATE TABLE IF NOT EXISTS status_log (...)")
+        # ... creates all tables
+```
+
+**How to Apply**
+- Automatic on first app startup
+- Database file created if not exists
+- Schema upgraded via `CREATE TABLE IF NOT EXISTS`
+
+**How to Rollback**
+```bash
+# Delete database file
+rm data/health_metrics.db
+# App will recreate on next run
+```
+
+**Schema Changes**
+To add columns:
+```python
+# In database.py _init_database()
+cursor.execute("ALTER TABLE status_log ADD COLUMN new_field TEXT")
+```
+
+### Data Retention
+
+**Automatic Cleanup** (scheduler.py)
+```python
+# Runs every scheduler cycle
+self.database.cleanup_old_data(days=7)
+```
+
+- Deletes `status_log` records older than 7 days
+- Deletes resolved incidents older than 7 days
+- Deletes acknowledged alerts older than 7 days
+- Configurable via `DATABASE_RETENTION_DAYS` env var
+
+**Manual Cleanup**
+```bash
+sqlite3 data/health_metrics.db
+> DELETE FROM status_log WHERE created_at < datetime('now', '-30 days');
+> VACUUM;
+```
+

+
+## 8. Frontend Structure & Conventions
+
+### Build System
+
+**Node.js Monitor Dashboard**
+- **Framework**: None (vanilla HTML/CSS/JavaScript)
+- **Build**: Not required - `dashboard.html` is served directly
+- **Server**: `python3 -m http.server 8080` or `npm run dashboard`
+
+**Gradio Interface**
+- **Framework**: Gradio 4.14.0
+- **Build**: None (Gradio handles compilation internally)
+- **Components**: Pre-built Gradio components (gr.DataFrame, gr.Plot, gr.Button, etc.)
+
+### Routing
+
+**dashboard.html** (No routing - single page)
+- All content in one HTML file
+- JavaScript handles dynamic updates
+- Fetches `api-monitor-report.json` via AJAX
+
+**Gradio** (Tab-based navigation)
+```python
+with gr.Blocks(theme=gr.themes.Soft()) as app:
+    with gr.Tab("Dashboard"):
+        # Dashboard components
+    with gr.Tab("Analytics"):
+        # Analytics components
+    # ... 5 tabs total
+```
+
+### State Management
+
+**dashboard.html**
+- No formal state management
+- DOM updates via vanilla JavaScript
+- Global variables for current report
+
+**Gradio**
+- Component state managed by Gradio framework
+- Global variables for shared state:
+  ```python
+  current_results = []  # Latest health check results
+  last_check_time = None
+  ```
+- Database serves as persistent state store
+
+### Theming
+
+**dashboard.html**
+```css
+/* Gradient background */
+background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
+
+/* Card shadows */
+box-shadow: 0 10px 30px rgba(0,0,0,0.2);
+
+/* Status colors */
+.online { color: #10b981; }
+.degraded { color: #f59e0b; }
+.offline { color: #ef4444; }
+```
+
+**Gradio**
+```python
+gr.Blocks(theme=gr.themes.Soft())
+# Uses Gradio's Soft theme
+# Custom CSS can be added via css= parameter
+```
+
+### Component Conventions
+
+**dashboard.html**
+- BEM-like naming: `.stat-card`, `.category-section`
+- Status badges: 🟢 🟡 🔴 (emoji)
+- Responsive grid: `grid-template-columns: repeat(auto-fit, minmax(250px, 1fr))`
+
+**Gradio Components**
+```python
+# Naming convention: {purpose}_{type}
+status_df = gr.DataFrame(label="Resource Status")
+refresh_btn = gr.Button("Refresh", variant="primary")
+category_dropdown = gr.Dropdown(choices=["All", ...], value="All")
+```
+
+### Where to Add Features
+
+**New Tab in Gradio**
+```python
+# In app_gradio.py, after existing tabs
+with gr.Tab("Your New Tab"):
+    with gr.Column():
+        gr.Markdown("## Your Feature")
+        # Add components
+        your_output = gr.Textbox()
+        your_button = gr.Button("Action")
+
+    # Wire up event handler
+    your_button.click(
+        fn=your_function,
+        inputs=[],
+        outputs=[your_output]
+    )
+```
+
+**New Chart in Analytics**
+```python
+# In app_gradio.py, create_analytics_charts() function
+def create_analytics_charts():
+    # ... existing charts ...
+
+    # Add new chart
+    fig_new = px.bar(data, x='category', y='value', title="New Metric")
+    return fig_uptime, fig_response, fig_new  # Add to return tuple
+
+# Update outputs in analytics_tab
+analytics_btn.click(
+    fn=create_analytics_charts,
+    outputs=[uptime_chart, response_chart, new_chart]  # Add new output
+)
+```
+
+**New Section in dashboard.html**
+```html
+<!-- After existing category sections -->
+<div class="category-section">
+    <h2 class="category-title">📊 YOUR NEW SECTION</h2>
+    <div class="resource-grid" id="your-section">
+        <!-- JavaScript will populate this -->
+    </div>
+</div>
+```
+
+```javascript
+// In <script> section, add to renderReport()
+function renderYourSection(data) {
+    const container = document.getElementById('your-section');
+    container.innerHTML = data.map(item => `
+        <div class="resource-card">...</div>
+    `).join('');
+}
+```

+
+**Python Tests**
+- **Framework**: Built-in `requests` library (test_aggregator.py)
+- **Type**: Integration tests (black-box API testing)
+- **Runner**: Python interpreter (no pytest/unittest)
+
+**Node.js Tests**
+- **Framework**: None currently
+- **Validation**: Manual via `node api-monitor.js` output inspection
+
+### How to Run Tests
+
+**FastAPI Integration Tests**
+```bash
+# Start the FastAPI server first
+python app.py &
+sleep 5  # Wait for startup
+
+# Run tests
+python test_aggregator.py
+
+# Example output:
+# ✓ PASSED: Health Check
+# ✓ PASSED: List Resources
+# ✓ PASSED: Query CoinGecko
+# ...
+# Total: 10 passed, 0 failed
+```
+
+**Manual Testing (Node.js)**
+```bash
+# Run health check
+node api-monitor.js
+
+# Verify output
+cat api-monitor-report.json | jq '.summary'
+
+# Expected:
+# {
+#   "totalResources": 52,
+#   "onlineResources": 48,
+#   "overallHealth": 92.3
+# }
+```
+
+**Gradio UI Testing**
+```bash
+# Start Gradio
+python app_gradio.py
+
+# Open browser: http://localhost:7860
+# Manual checks:

+
+## 11. Extensibility Playbook
+
+### How to Add a New API Endpoint (FastAPI)
+
+**Step 1**: Define Pydantic model (if needed)
+```python
+# In app.py
+class NewFeatureRequest(BaseModel):
+    param1: str
+    param2: Optional[int] = None
+```
+
+**Step 2**: Create endpoint function
+```python
+# In app.py
+@app.post("/new-feature")
+async def new_feature(request: NewFeatureRequest):
+    """Your new feature"""
+    # Process request
+    result = process_feature(request.param1, request.param2)
+
+    # Log to database (optional)
+    log_query("new_feature", "custom", "", "success", 0.1)
+
+    return {
+        "success": True,
+        "data": result,
+        "timestamp": datetime.now().isoformat()
+    }
+```
+
+**Step 3**: Test endpoint
+```bash
+curl -X POST http://localhost:7860/new-feature \
+  -H "Content-Type: application/json" \
+  -d '{"param1": "test", "param2": 123}'
+```
+
+### How to Add a New UI Page (Gradio Tab)
+
+**Step 1**: Create tab in app_gradio.py
+```python
+# After existing tabs
+with gr.Tab("Your New Feature"):
+    with gr.Column():
+        gr.Markdown("## New Feature Description")
+
+        # Input components
+        input_text = gr.Textbox(label="Input", placeholder="Enter value...")
+        process_btn = gr.Button("Process", variant="primary")
+
+        # Output components
+        output_result = gr.Textbox(label="Result", interactive=False)
+        output_chart = gr.Plot(label="Visualization")
+
+    # Wire up event handler
+    process_btn.click(
+        fn=your_processing_function,
+        inputs=[input_text],
+        outputs=[output_result, output_chart]
+    )
+
+def your_processing_function(input_value: str):
+    """Process the input and return results"""
+    # Your logic here
+    result_text = f"Processed: {input_value}"
+
+    # Create chart
+    fig = px.bar(x=['A', 'B', 'C'], y=[1, 2, 3])
+
+    return result_text, fig
+```
+
+**Step 2**: Test in browser
+```bash
+python app_gradio.py
+# Open: http://localhost:7860
+# Click "Your New Feature" tab
+```
+
+### How to Add a New Background Job (Scheduler)
+
+**Step 1**: Create job function in scheduler.py
+```python
+# In scheduler.py
+def _your_new_job(self):
+    """Your scheduled task"""
+    try:
+        logger.info("Running your new job...")
+
+        # Your logic here
+        results = perform_task()
+
+        # Save to database
+        self.database.save_custom_data(results)
+
+        logger.info("Job completed successfully")
+
+    except Exception as e:
+        logger.error(f"Job failed: {e}")
+```
+
+**Step 2**: Schedule the job
+```python
+# In scheduler.py start() method
+self.scheduler.add_job(
+    func=self._your_new_job,
+    trigger=IntervalTrigger(hours=1),  # Every hour
+    id='your_job_id',
+    name='Your Custom Job',
+    replace_existing=True
+)
+```
+
+**Step 3**: Test manually
+```python
+# In Python REPL
+from scheduler import BackgroundScheduler
+from monitor import APIMonitor
+from database import Database
+from config import config
+
+monitor = APIMonitor(config)
+db = Database()
+scheduler = BackgroundScheduler(monitor, db)
+
+# Trigger manually
+scheduler._your_new_job()
+```
+
+### How to Add a New Third-Party Provider
+
+**Step 1**: Add to `all_apis_merged_2025.json`
+```json
+{
+  "discovered_keys": {
+    "your_new_provider": "your_api_key_here"
+  },
+  "raw_files": [
+    {
+      "content": "YourProvider: your_api_key_here"
+    }
+  ]
+}
+```
+
+**Step 2**: Add resource definition in config.py
+```python
+# In config.py _load_fallback_resources() or parse logic
+{
+    "category": "Market Data",
+    "name": "YourProvider",
+    "url": "https://api.yourprovider.com/v1",
+    "key": self.api_keys.get('your_new_provider', ''),
+    "free": False,
+    "rateLimit": "1000/day",
+    "desc": "Your provider description",
+    "endpoint": "/market/prices",
+    "tier": 2
+}
+```
+
+**Step 3**: Add health check logic in monitor.py (if custom)
+```python
+# In monitor.py check_endpoint()
+# Custom headers
+if 'yourprovider' in provider_name.lower():
+    headers['X-API-KEY'] = api_key
+    headers['Custom-Header'] = 'value'
+```
+
+**Step 4**: Add to Node.js monitor (optional)
+```javascript
+// In api-monitor.js API_REGISTRY
+marketData: {
+  yourprovider: [
+    {
+      name: 'YourProvider',
+      url: 'https://api.yourprovider.com/v1',
+      keyName: 'your_new_provider',
+      keyIndex: 0,
+      testEndpoint: '/health',
+      tier: 2
+    }
+  ]
+}
+```
+
+**Step 5**: Test the new provider
+```bash
+# Python test
+python -c "from config import config; print(config.get_all_resources())"
+
+# Full health check
+python app_gradio.py
+# Click "Run Health Check", verify new provider appears
+```
+
+### Code Style/Linting Conventions
+
+**Python** (PEP 8)
+- Use 4 spaces for indentation
+- Maximum line length: 100 characters (flexible)
+- Docstrings: Google style

+    """
+    Brief description.
+
+    Args:
+        param1: Description of param1
+        param2: Description of param2
+
+    Returns:
+        Description of return value
+    """
+```
+
+**JavaScript** (Informal)
+- Use 2 spaces for indentation

+
+## 12. Risks, Limits, and TODOs
+
+### Known Limitations
+
+**1. SQLite Concurrency**
+- ❌ **Issue**: SQLite locks during writes, blocking concurrent operations
+- **Impact**: High-frequency writes may cause "database locked" errors
+- **Mitigation**: Use WAL mode, add retry logic
+- **TODO**: Consider PostgreSQL for production with >10 req/sec
+
+**2. API Rate Limits**
+- ❌ **Issue**: Free tier APIs have strict limits (e.g., CMC: 333/day)
+- **Impact**: Frequent monitoring exhausts daily quota
+- **Mitigation**: Implemented caching, configurable intervals
+- **TODO**: Add rate limit tracking per provider, auto-throttle
+
+**3. No Authentication**
+- ❌ **Issue**: FastAPI/Gradio endpoints are public (no auth)
+- **Impact**: Anyone can query your APIs, deplete rate limits
+- **Mitigation**: Deploy on private HF Space or add IP whitelist
+- **TODO**: Implement API key authentication for /query endpoint
+
+**4. Single Point of Failure**
+- ❌ **Issue**: If host goes down, entire service is unavailable
+- **Impact**: No redundancy for critical monitoring
+- **Mitigation**: Use managed platforms (HF Spaces has 99% uptime)
+- **TODO**: Multi-region deployment (HF Spaces + Heroku)
+
+**5. No Real-Time WebSockets**
+- ❌ **Issue**: Gradio uses polling, not true real-time updates
+- **Impact**: 30s delay before UI reflects new data
+- **Mitigation**: Acceptable for monitoring use case
+- **TODO**: Consider FastAPI WebSocket for push updates
+
+### Technical Debt
+
+**1. Hardcoded API Keys**
+- **Location**: `config.py` lines 36-44, `api-monitor.js` (in JSON)
+- **Issue**: Keys committed to repo (safe for public tier, but bad practice)
+- **TODO**: Remove all hardcoded keys, enforce env var usage
+
+**2. No Unit Tests**
+- **Coverage**: ~0% (only integration tests)
+- **Issue**: Refactoring risks breaking existing features
+- **TODO**: Add pytest suite with 80% coverage target
+
+**3. Magic Numbers**
+- **Examples**: Timeouts (10s), intervals (5 min), retention (7 days)
+- **Issue**: Hard to tune without code changes
+- **TODO**: Move to config file or database
+
+**4. Mixed Languages**
+- **Issue**: Node.js + Python requires two runtimes
+- **TODO**: Rewrite api-monitor.js in Python for consistency
+
+**5. No Logging Infrastructure**
+- **Issue**: Logs go to stdout, no structured logging or aggregation
+- **TODO**: Add structured logging (JSON), ship to external service (Datadog, ELK)
+
+### Security Concerns
+
+**1. API Key Exposure**
+- ⚠️ **Risk**: Keys visible in logs (first/last 4 chars)
+- **Mitigation**: Mask in logs, use secrets managers
+- **TODO**: Integrate with HF Secrets, AWS Secrets Manager
+
+**2. SQL Injection** (Low risk)
+- ⚠️ **Risk**: SQL queries use parameterized statements (safe)
+- **Status**: ✅ Not vulnerable (using `?` placeholders)
+
+**3. SSRF via /query Endpoint**
+- ⚠️ **Risk**: User could query internal services via CORS proxy
+- **Mitigation**: Whitelist allowed base URLs
+- **TODO**: Add URL validation, block private IPs (192.168.*, 10.*, 127.*)
+
+**4. DoS via Rate Limit Exhaustion**
+- ⚠️ **Risk**: Attacker spams /query, exhausts API quotas
+- **Mitigation**: None currently
+- **TODO**: Add rate limiting (Flask-Limiter), API key per user
+
+### Rate Limit Exposure
+
+**Current Limits** (Free Tiers):
+
+| Provider | Limit | Monitoring Impact | Status |
+|----------|-------|-------------------|--------|
+| **CoinGecko** | 10-30/min | ✅ Safe (1 call/5min) | OK |
+| **CoinMarketCap** | 333/day | ⚠️ At risk (288 calls/day @ 5min interval) | **High usage** |
+| **Etherscan** | 5/sec, 100K/day | ✅ Safe (1 call/5min) | OK |
+| **NewsAPI** | 100/day | ⚠️ At risk if queried frequently | Monitor closely |
+| **Infura** | 100K/day | ✅ Safe | OK |
+
+**Mitigation**:
+- ✅ Caching (60s TTL) reduces duplicate calls
+- ✅ Configurable intervals (5 min default)
+- ❌ **TODO**: Track usage per provider, alert at 80% threshold
+
+### Single Points of Failure (SPOFs)
+
+**Identified SPOFs**:
+
+1. **Database File** (`health_metrics.db`)
+   - Risk: Corruption or deletion loses all history
+   - Mitigation: Daily backups (not implemented)
+   - TODO: Add automated backup to S3/cloud storage
+
+2. **Scheduler Thread**
+   - Risk: If APScheduler crashes, monitoring stops
+   - Mitigation: Gradio restarts on crash
+   - TODO: Add health check endpoint for scheduler status
+
+3. **Single API Key per Provider**
+   - Risk: If Etherscan key banned, no Ethereum data
+   - Mitigation: Backup keys implemented for CMC, Etherscan
+   - TODO: Auto-rotate to backup on 429 errors
+
+4. **Dependency on Hugging Face**
+   - Risk: If HF Spaces has outage, service down
+   - Mitigation: Can deploy to Heroku/Railway
+   - TODO: Multi-cloud deployment script
+

+- `data_collection` - Read historical data freshness
+
+### Indexes Required (Already Exist)
+
+- `rate_limit_usage.timestamp` - ✓ Indexed
+- `rate_limit_usage.provider_id` - ✓ Indexed
+- `data_collection.actual_fetch_time` - ✓ Indexed
+- `data_collection.provider_id` - ✓ Indexed
+
+**No schema changes required.**
+
+---
+
+## Deployment Notes
+
+### Environment Variables
+
+No new environment variables required.
+
+### Configuration Changes
+
+No configuration file changes required.
+
+### Dependencies
+
+No new dependencies added. Uses existing:
+- FastAPI (query parameters, routing)
+- SQLAlchemy (database queries)
+- pydantic (validation)
+
+### Reverse Proxy (Optional)
+
+Recommended nginx/cloudflare rate limiting:
+
+```nginx
+# Rate limit chart endpoints
+location /api/charts/ {
+    limit_req zone=charts burst=10 nodelay;
+    limit_req_status 429;
+    proxy_pass http://backend;
+}
+
+# Define rate limit zone (60 req/min per IP)
+limit_req_zone $binary_remote_addr zone=charts:10m rate=60r/m;
+```
+
+---
+
+## Monitoring & Alerting
+
+### Recommended Metrics
+
+Add to your monitoring system (Prometheus, Datadog, etc.):
+
+```yaml
+# Response time histogram
+chart_response_time_seconds{endpoint, quantile}
+
+# Request counter
+chart_requests_total{endpoint, status}
+
+# Error rate
+chart_errors_total{endpoint, error_type}
+
+# Provider-specific metrics
+ratelimit_usage_pct{provider}
+freshness_staleness_min{provider}
+```
+
+### Recommended Alerts
+
+```yaml
+# Critical: Rate limit near exhaustion
+- alert: RateLimitCritical
+  expr: ratelimit_usage_pct > 90
+  for: 3h
+
+# Critical: Data stale
+- alert: DataStaleCritical
+  expr: freshness_staleness_min > ttl_min * 2
+  for: 15m
+
+# Warning: Chart endpoint slow
+- alert: ChartEndpointSlow
+  expr: histogram_quantile(0.95, chart_response_time_seconds) > 0.5
+  for: 10m
+```
+
+---
+
+## Rollback Plan
+
+If issues arise after deployment:
+
+### Option 1: Feature Flag (Recommended)
+
+```python
+# In api/endpoints.py, wrap endpoints with feature flag
+if config.get("ENABLE_CHART_ENDPOINTS", False):
+    @router.get("/charts/rate-limit-history")
+    async def get_rate_limit_history(...):
+        ...
+```
+
+### Option 2: Git Revert
+
+```bash
+# Revert this PR
+git revert <commit-hash>
+
+# Or cherry-pick revert of specific files
+git checkout <previous-commit> -- api/endpoints.py
+```
+
+### Option 3: Emergency Disable (Nginx)
+
+```nginx
+# Block chart endpoints temporarily
+location /api/charts/ {
+    return 503;
+}
+```
+
+---
+
+## Known Limitations
+
+1. **No caching layer** - Each request hits database (acceptable for now)
+2. **Max 5 providers** - Hard limit (by design)
+3. **Max 168 hours** - Hard limit (1 week, by design)
+4. **Hourly granularity** - Not configurable (by design)
+5. **No real-time updates** - Requires polling or WebSocket (future work)
+
+---
+
+## Future Work

+
+## Additional Notes
+
+### Why This Implementation?
+
+1. **Hourly bucketing** - Balances granularity with performance and data volume
+2. **Max 5 providers** - Prevents chart clutter and ensures good UX
+3. **168 hour limit** - One week is sufficient for most monitoring use cases
+4. **Allow-list validation** - Prevents enumeration and ensures data integrity
+5. **In-memory bucketing** - Faster than complex SQL GROUP BY queries
+6. **Gap filling** - Ensures consistent chart rendering (no missing x-axis points)
+
+### Performance Considerations
+
+- Database queries use indexed columns (timestamp, provider_id)
+- Limited result sets (max 5 providers * 168 hours = 840 points per query)
+- Simple aggregation (max one record per hour per provider)
+- No expensive JOINs or subqueries
+
+### Security Considerations
+
+- No user authentication required (internal monitoring API)
+- Rate limiting recommended at reverse proxy level
+- Input validation prevents common injection attacks
+- Error messages are safe (no stack traces, SQL fragments)
+
+---
+
+## Questions for Reviewers
+
+1. Should we add caching at this stage or defer to later PR?
+2. Is 168 hours (1 week) an appropriate max, or should it be configurable?
+3. Should we add authentication/API keys for these endpoints?
+4. Do we want category-level aggregation in this PR or separate?

+
+## 📈 Status Classification
+
+The monitor automatically classifies each API into one of five states:
+
+| Status | Success Rate | Response Time | Description |
+|--------|--------------|---------------|-------------|
+| 🟢 **ONLINE** | ≥95% | <2 seconds | Fully operational, optimal performance |
+| 🟡 **DEGRADED** | 80-95% | 2-5 seconds | Functional but slower than normal |
+| 🟠 **SLOW** | 70-80% | 5-10 seconds | Significant performance issues |
+| 🔴 **UNSTABLE** | 50-70% | Any | Frequent failures, unreliable |
+| ⚫ **OFFLINE** | <50% | Any | Not responding or completely down |
+
+**Classification Logic:**
+- Based on last 10 health checks
+- Success rate = successful responses / total attempts
+- Response time = average of successful requests only
+
+---
+
+## ⚠️ Alert Conditions
+
+The system triggers alerts for:
+
+### Critical Alerts
+- ❌ TIER-1 API offline (Etherscan, CoinGecko, Infura, Alchemy)
+- ❌ All providers in a category offline
+- ❌ Zero available resources for essential data type
+
+### Warning Alerts
+- ⚠️ Response time >5 seconds sustained for 15 minutes
+- ⚠️ Success rate dropped below 80%
+- ⚠️ Single Point of Failure (only 1 provider available)
+- ⚠️ Rate limit reached (>80% consumed)
+
+### Info Alerts
+- ℹ️ API key approaching expiration
+- ℹ️ SSL certificate expires within 7 days
+- ℹ️ New resource added to registry
+
+---
+
+## 🔄 Failover Management
+
+### Automatic Failover Chains
+
+The system builds intelligent failover chains for each data type:
+
+```javascript
+// Example: Ethereum Price Failover Chain
+const failoverConfig = require('./failover-config.json');
+
+async function getEthereumPrice() {
+  const chain = failoverConfig.chains.ethereumPrice;
+
+  for (const resource of chain) {
+    try {
+      // Try primary first (CoinGecko)
+      const response = await fetch(resource.url + '/api/v3/simple/price?ids=ethereum&vs_currencies=usd');
+      const data = await response.json();
+      return data.ethereum.usd;
+    } catch (error) {
+      console.log(`${resource.name} failed, trying next in chain...`);
+      continue;
+    }
+  }
+
+  throw new Error('All resources in failover chain failed');
+}
+```
+
+### Priority Tiers
+
+**TIER-1 (CRITICAL):** Etherscan, BscScan, CoinGecko, Infura, Alchemy
+**TIER-2 (HIGH):** CoinMarketCap, CryptoCompare, TronScan, NewsAPI
+**TIER-3 (MEDIUM):** Alternative.me, Reddit, CORS proxies, public RPCs
+**TIER-4 (LOW):** Experimental APIs, community nodes, backup sources
+
+Failover chains prioritize lower tier numbers first.

+## 🛠️ Troubleshooting
+
+### "Failed to load registry"
+
+**Cause:** `all_apis_merged_2025.json` not found
+**Solution:** Ensure the file exists in the same directory
+
+### "Request timeout" errors
+
+**Cause:** API endpoint is slow or down
+**Solution:** Normal behavior, will be classified as SLOW/OFFLINE
+
+### "CORS error" in dashboard
+
+**Cause:** Report JSON not accessible
+**Solution:** Run `npm run dashboard` to start local server
+
+### Rate limit errors (429)
+
+**Cause:** Too many requests to API
+**Solution:** Increase `CHECK_INTERVAL` or reduce resource list

+```javascript
+// Create a client wrapper
+class CryptoAggregator {
+  constructor(baseUrl = 'https://your-space.hf.space') {
+    this.baseUrl = baseUrl;
+  }
+
+  async query(resourceType, resourceName, endpoint = '', params = {}) {
+    const response = await fetch(`${this.baseUrl}/query`, {
+      method: 'POST',
+      headers: { 'Content-Type': 'application/json' },
+      body: JSON.stringify({

+    return await response.json();
+  }
+
+  async getStatus() {
+    const response = await fetch(`${this.baseUrl}/status`);
+    return await response.json();
+  }
+
+  async getHistory(limit = 100) {
+    const response = await fetch(`${this.baseUrl}/history?limit=${limit}`);
+    return await response.json();
+  }
+}
+
+// Usage
+const aggregator = new CryptoAggregator();
+
+// Get Bitcoin price
+const price = await aggregator.query('market_data', 'coingecko', '/simple/price', {
+  ids: 'bitcoin',
+  vs_currencies: 'usd'
+});
+
+// Check system status
+const status = await aggregator.getStatus();
+console.log(`${status.online}/${status.total_resources} resources online`);
+```
+
+## Monitoring & Maintenance
+
+- Check `/status` regularly to ensure resources are online
+- Monitor `/history/stats` for usage patterns and success rates
+- Review consecutive failures in the database
+- Update API keys when needed
+
+## License
+
+This aggregator is built for educational and development purposes.
+API keys should be kept secure and rate limits respected.
+
+## Support
+
+For issues or questions:
+1. Check the `/health` endpoint
+2. Review `/history` for error patterns
+3. Verify resource status with `/status`
+4. Check individual resource documentation

+
+## Overview
+
+The Crypto API Monitoring System provides comprehensive WebSocket APIs for real-time streaming of all services. All WebSocket endpoints support:
+
+- **Subscription-based routing**: Subscribe only to services you need
+- **Real-time updates**: Live data streaming at service-specific intervals
+- **Bi-directional communication**: Send commands and receive responses
+- **Connection management**: Automatic reconnection and heartbeat
+- **Multiple connection patterns**: Master endpoint, service-specific endpoints, or auto-subscribe
+
+---
+
+## Quick Start
+
+### Basic Connection
+
+```javascript
+// Connect to the master endpoint
+const ws = new WebSocket('ws://localhost:7860/ws/master');
+
+ws.onopen = () => {
+    console.log('Connected!');
+
+    // Subscribe to market data
+    ws.send(JSON.stringify({
+        action: 'subscribe',
+        service: 'market_data'
+    }));
+};
+
+ws.onmessage = (event) => {
+    const message = JSON.parse(event.data);
+    console.log('Received:', message);
+};
+```
+
+### Python Example
+
+```python
+import asyncio
+import websockets
+import json
+
+async def connect():
+    uri = "ws://localhost:7860/ws/master"
+    async with websockets.connect(uri) as websocket:
+        # Subscribe to whale tracking
+        await websocket.send(json.dumps({
+            "action": "subscribe",
+            "service": "whale_tracking"
+        }))
+
+        # Receive messages
+        async for message in websocket:
+            data = json.loads(message)
+            print(f"Received: {data}")
+
+asyncio.run(connect())
+```

+
+---
+
+## Error Handling
+
+### Connection Errors
+
+If a connection fails or is lost, implement exponential backoff:
+
+```javascript
+class ReconnectingWebSocket {
+    constructor(url) {
+        this.url = url;
+        this.reconnectDelay = 1000;
+        this.maxReconnectDelay = 30000;
+        this.connect();
+    }
+
+    connect() {
+        this.ws = new WebSocket(this.url);
+
+        this.ws.onclose = () => {
+            console.log(`Reconnecting in ${this.reconnectDelay}ms...`);
+            setTimeout(() => {
+                this.reconnectDelay = Math.min(
+                    this.reconnectDelay * 2,
+                    this.maxReconnectDelay
+                );
+                this.connect();
+            }, this.reconnectDelay);
+        };
+
+        this.ws.onopen = () => {
+            console.log('Connected');
+            this.reconnectDelay = 1000; // Reset delay on successful connection
+        };
+    }
+}
+```
+
+### Message Errors
+
+Handle error messages from the server:
+
+```javascript
+ws.onmessage = (event) => {
+    const message = JSON.parse(event.data);
+
+    if (message.type === 'error') {
+        console.error('Server error:', message.data.message);
+
+        // Handle specific errors
+        if (message.data.message.includes('Invalid service')) {
+            console.log('Available services:', message.data.available_services);
+        }
+    }
+};
+```
+
+---
+
+## Best Practices
+
+1. **Subscribe Only to What You Need**: Minimize bandwidth by subscribing only to required services
+2. **Implement Reconnection Logic**: Handle network interruptions gracefully
+3. **Use Heartbeats**: Implement ping/pong to detect connection issues early
+4. **Handle Backpressure**: Process messages efficiently to avoid queue buildup
+5. **Clean Up Subscriptions**: Unsubscribe when components unmount or services are no longer needed
+6. **Use Service-Specific Endpoints**: For single-service needs, use dedicated endpoints to reduce initial setup
+7. **Monitor Connection Status**: Track connection state and subscriptions in your application
+8. **Implement Error Boundaries**: Gracefully handle and display connection/data errors

+## WebSocket Usage Example
+
+### JavaScript Client:
+```javascript
+const ws = new WebSocket('ws://localhost:7860/ws/live');
+
+ws.onopen = () => {
+    console.log('Connected to WebSocket');
+};
+
+ws.onmessage = (event) => {
+    const message = JSON.parse(event.data);
+
+    switch(message.type) {
+        case 'connection_established':
+            console.log('Client ID:', message.client_id);
+            break;
+
+        case 'status_update':
+            console.log('System Status:', message.system_metrics);
+            break;
+
+        case 'rate_limit_alert':
+            console.warn(`Rate limit alert: ${message.provider} at ${message.percentage}%`);
+            break;
+
+        case 'provider_status_change':
+            console.log(`Provider ${message.provider}: ${message.old_status} → ${message.new_status}`);
+            break;
+
+        case 'ping':
+            // Respond with pong
+            ws.send(JSON.stringify({ type: 'pong' }));
+            break;
+    }
+};
+
+ws.onclose = () => {
+    console.log('Disconnected from WebSocket');
+};
+
+ws.onerror = (error) => {
+    console.error('WebSocket error:', error);
+};
+```

+
+## Dependencies
+
+All required packages are in `requirements.txt`:
+- fastapi
+- uvicorn[standard]
+- websockets
+- sqlalchemy
+- apscheduler
+- aiohttp
+- python-dotenv
+
+## Security Considerations
+
+1. **CORS**: Currently set to allow all origins. In production, specify allowed origins:
+   ```python
+   allow_origins=["https://yourdomain.com"]
+   ```
+
+2. **API Keys**: Masked in responses using `_mask_key()` method
+
+3. **Rate Limiting**: Built-in per-provider rate limiting
+
+4. **WebSocket Authentication**: Can be added by implementing token validation in connection handler
+
+5. **Database**: SQLite is suitable for development. Consider PostgreSQL for production.
+
+## Monitoring & Observability
+
+- **Logs**: Comprehensive logging via `utils.logger`
+- **Health Checks**: `/health` endpoint with component status
+- **Metrics**: System metrics tracked in database
+- **Alerts**: Built-in alerting system
+- **WebSocket Stats**: `/ws/stats` endpoint
+
+## Next Steps (Optional Enhancements)
+
+1. Add WebSocket authentication
+2. Implement topic-based subscriptions
+3. Add message queuing (Redis/RabbitMQ)
+4. Implement horizontal scaling
+5. Add Prometheus metrics export
+6. Implement rate limiting per WebSocket client
+7. Add message replay capability
+8. Implement WebSocket reconnection logic
+9. Add GraphQL API support
+10. Implement API versioning
+
+## Troubleshooting
+
+### WebSocket won't connect:
+- Check firewall settings
+- Verify port 7860 is accessible
+- Check CORS configuration
+
+### Database errors:
+- Ensure `data/` directory exists
+- Check file permissions
+- Verify SQLite is installed
+
+### Scheduler not starting:
+- Check database initialization
+- Verify provider configurations
+- Check logs for errors
+
+### High memory usage:
+- Limit number of WebSocket connections
+- Implement connection pooling
+- Adjust database cleanup settings
+

+
+**Implementation Date**: 2025-11-11
+**Version**: 2.0.0
+**Status**: Production Ready ✅
