---

## ✅ PHASE 2: MOCK DATA ENDPOINTS FIXED

### 2.1 GET /api/market - FIXED ✅

**Before:**
```python
# Hardcoded mock data
return {"cryptocurrencies": [{"price": 43250.50, ...}]}
```

**After:**
```python
# Real CoinGecko data
result = await get_coingecko_simple_price()
if not result.get("success"):
    raise HTTPException(status_code=503, detail={...})
# Transform and save to database
db.save_price({...})
return {"cryptocurrencies": [...], "provider": "CoinGecko"}
```

**Verification:**
```bash
curl localhost:7860/api/market | jq '.cryptocurrencies[0].price'
# Should return REAL current price, not 43250.50
```

### 2.2 GET /api/sentiment - FIXED ✅

**Before:**
```python
# Hardcoded fear_greed_index: 62
return {"fear_greed_index": {"value": 62, "classification": "Greed"}}
```

**After:**
```python
# Real Alternative.me data
result = await get_fear_greed_index()
if not result.get("success"):
    raise HTTPException(status_code=503, detail={...})
return {"fear_greed_index": {...}, "provider": "Alternative.me"}
```

**Verification:**
```bash
curl localhost:7860/api/sentiment | jq '.fear_greed_index.value'
# Should return REAL current index, not always 62
```

### 2.3 GET /api/trending - FIXED ✅

**Before:**
```python
# Hardcoded Solana/Cardano
return {"trending": [{"name": "Solana", ...}, {"name": "Cardano", ...}]}
```

**After:**
```python
# Real CoinGecko trending endpoint
url = "https://api.coingecko.com/api/v3/search/trending"
async with manager.session.get(url) as response:
    data = await response.json()
    # Extract real trending coins
return {"trending": [...], "provider": "CoinGecko"}
```

**Verification:**
```bash
curl localhost:7860/api/trending | jq '.trending[0].name'
# Should return REAL current trending coin
```

### 2.4 GET /api/defi - FIXED ✅

**Before:**
```python
# Fake TVL data
return {"total_tvl": 48500000000, "protocols": [...]}
```

**After:**
```python
# Explicit 503 error when USE_MOCK_DATA=false
if USE_MOCK_DATA:
    return {"total_tvl": ..., "_mock": True}
raise HTTPException(status_code=503, detail={
    "error": "DeFi endpoint not implemented with real providers yet",
    "recommendation": "Set USE_MOCK_DATA=true for demo"
})
```

**Verification:**
```bash
curl -i localhost:7860/api/defi
# Should return HTTP 503 in real mode
# Or mock data with "_mock": true flag
```

### 2.5 POST /api/hf/run-sentiment - FIXED ✅

**Before:**
```python
# Fake keyword-based sentiment pretending to be ML
sentiment = "positive" if "bullish" in text else ...
```

**After:**
```python
# Explicit 501 error when USE_MOCK_DATA=false
if USE_MOCK_DATA:
    return {"results": ..., "_mock": True, "_warning": "keyword-based"}
raise HTTPException(status_code=501, detail={
    "error": "Real ML-based sentiment analysis is not implemented yet",
    "recommendation": "Set USE_MOCK_DATA=true for keyword-based demo"
})
```

**Verification:**
```bash
curl -i -X POST localhost:7860/api/hf/run-sentiment \
  -H "Content-Type: application/json" -d '{"texts": ["test"]}'
# Should return HTTP 501 in real mode
```

---

## ✅ PHASE 3: USE_MOCK_DATA FLAG IMPLEMENTED

### 3.1 Environment Variable - ADDED ✅

**Location:** `api_server_extended.py` (line 30)

```python
# USE_MOCK_DATA flag for testing/demo mode
USE_MOCK_DATA = os.getenv("USE_MOCK_DATA", "false").lower() == "true"
```

**Dockerfile Default:**
```dockerfile
ENV USE_MOCK_DATA=false
```

**Behavior:**
- `USE_MOCK_DATA=false` (default): All endpoints use real data or return 503/501
- `USE_MOCK_DATA=true`: Endpoints return mock data with `"_mock": true` flag

**Verification:**
```bash
# Test real mode
docker run -e USE_MOCK_DATA=false -p 7860:7860 crypto-monitor

# Test mock mode
docker run -e USE_MOCK_DATA=true -p 7860:7860 crypto-monitor
```

---

## ✅ PHASE 4: DATABASE INTEGRATION

### 4.1 Database Initialization - VERIFIED ✅

**File:** `database.py`

**Tables Created:**
- ✅ `prices` - Cryptocurrency price history
- ✅ `news` - News articles with sentiment
- ✅ `market_analysis` - Technical analysis data
- ✅ `user_queries` - Query logging

**Schema Verification:**
```python
db = get_database()
stats = db.get_database_stats()
# Returns: prices_count, news_count, unique_symbols, etc.
```

### 4.2 Market Data Write Integration - ADDED ✅

**Location:** `/api/market` endpoint

```python
# Save to database after fetching from CoinGecko
db.save_price({
    "symbol": coin_info["symbol"],
    "name": coin_info["name"],
    "price_usd": crypto_entry["price"],
    "volume_24h": crypto_entry["volume_24h"],
    "market_cap": crypto_entry["market_cap"],
    "percent_change_24h": crypto_entry["change_24h"],
    "rank": coin_info["rank"]
})
```

### 4.3 Market History Endpoint - ADDED ✅

**New Endpoint:** `GET /api/market/history`

**Parameters:**
- `symbol` (string): Cryptocurrency symbol (default: "BTC")
- `limit` (int): Number of records (default: 10)

**Implementation:**
```python
@app.get("/api/market/history")
async def get_market_history(symbol: str = "BTC", limit: int = 10):
    history = db.get_price_history(symbol, hours=24)
    return {"symbol": symbol, "history": history[-limit:], "count": len(history)}
```

**Verification:**
```bash
# Wait 5 minutes for data to accumulate, then:
curl "localhost:7860/api/market/history?symbol=BTC&limit=10" | jq
```

---

## ✅ PHASE 5: LOGS & RUNTIME DIRECTORIES

### 5.1 Directory Creation - VERIFIED ✅

**Dockerfile:**
```dockerfile
RUN mkdir -p logs data exports backups data/database data/backups
```

**Application Startup Check:**
```python
required_dirs = [Path("data"), Path("data/exports"), Path("logs")]
for directory in required_dirs:
    if not directory.exists():
        directory.mkdir(parents=True, exist_ok=True)
```

**Verification:**
```bash
docker run crypto-monitor ls -la /app/
# Should show: logs/, data/, exports/, backups/
```

---

## ✅ PHASE 6: VERIFICATION & TESTING

### 6.1 Syntax Validation - PASSED ✅

```bash
python3 -m py_compile api_server_extended.py  # ✅ No errors
python3 -m py_compile provider_fetch_helper.py  # ✅ No errors
python3 -m py_compile database.py              # ✅ No errors
```

### 6.2 Import Validation - PASSED ✅

**All imports verified:**
- ✅ `from collectors.sentiment import get_fear_greed_index`
- ✅ `from collectors.market_data import get_coingecko_simple_price`
- ✅ `from database import get_database`
- ✅ `from provider_manager import ProviderManager`

### 6.3 USE_MOCK_DATA Flag Detection - PASSED ✅
