## 🔒 Security Considerations | ملاحظات امنیتی

✅ **No API Keys Stored** - All data sources are free and public
✅ **Read-Only Operations** - Only fetches data, never modifies external sources
✅ **Rate Limiting** - Respects source rate limits
✅ **Input Validation** - Pydantic models validate all inputs
✅ **SQL Injection Protection** - Uses parameterized queries
✅ **CORS Enabled** - Configure as needed for your use case

---

## 🎓 Use Cases | موارد استفاده

### 1. Trading Bots
Use the API to get real-time prices and sentiment for automated trading

### 2. Portfolio Trackers
Build a portfolio tracker with historical price data

### 3. News Aggregators
