## Expected Response Formats

### Success Response

{
  "success": true,
  "data": { ... },
  "timestamp": "2025-12-12T10:00:00Z"
}
```

### Error Response

{
  "success": false,
  "error": "Error message",
  "timestamp": "2025-12-12T10:00:00Z"
}
```

## Common Issues & Solutions

### 1. 404 Not Found
- Verify endpoint path is correct
- Check if router is loaded: `curl http://localhost:7860/api/routers`
- Ensure server is running on correct port

### 2. 429 Rate Limited
- External API (like CoinGecko) rate limit reached
- System will automatically fallback to alternative providers
- Wait a few minutes and retry

### 3. 500 Internal Server Error
- Check server logs for detailed error
- Verify all dependencies are installed: `pip install -r requirements.txt`
- Ensure database is initialized

### 4. CORS Errors (Browser)
- CORS is enabled by default for all origins
- If issues persist, check browser console for specific error
- Verify request headers are properly set

### 5. Database Connection Issues
- SQLite database should auto-initialize
- Check `data/` directory exists and is writable
- Review logs for database errors

## Performance Benchmarks

Expected response times:
- Health checks: < 50ms
- Market data: 100-500ms (depends on external API)
- AI model inference: 200-1000ms (depends on model)
- Database queries: < 100ms
- Static files: < 50ms

## Integration Checklist

- [ ] Server starts without errors on port 7860
- [ ] GET `/api/health` returns 200
- [ ] GET `/` serves dashboard UI
- [ ] All documented endpoints respond (not all 404)
- [ ] UI pages load correctly
- [ ] API calls from frontend work
- [ ] No CORS errors in browser console
- [ ] Database initializes without errors
- [ ] Static files serve correctly
- [ ] WebSocket connections work (optional)

## Automated Testing

Run the comprehensive test suite:

```bash
# Test local deployment
python test_endpoints_comprehensive.py

# Test HuggingFace Space
python test_endpoints_comprehensive.py https://your-space.hf.space

# Expected output: 80%+ success rate
```

## Support

If endpoints are failing:
1. Check HuggingFace Space logs for errors
2. Verify all environment variables are set
3. Ensure requirements.txt dependencies are installed
4. Test endpoints individually using curl
5. Check browser console for client-side errors

## Notes

- Some endpoints may return fallback data if external APIs are unavailable
- OHLCV data requires external API access (Binance, HuggingFace datasets)
- AI model endpoints work without models loaded (return mock data)
- Database endpoints gracefully degrade if database is unavailable
