  -H "X-API-Key: castor_d167aa169b5e4219a66779e45fbaaefe" \
  -d '{
    "product": "Castor",
    "start_date": "2025-12-01",
    "end_date": "2026-01-31"
  }'
```

---

### 3. JavaScript Integration
```javascript
const forecast = await fetch('http://127.0.0.1:5000/api/forecast', {
  method: 'POST',
  headers: {
    'X-API-Key': 'castor_d167aa169b5e4219a66779e45fbaaefe',

  }
)

forecast_data = response.json()
for item in forecast_data['forecast'][:5]:
    print(f"{item['date']}: ARIMA={item['arima_price']}, LSTM={item['lstm_price']}")
```

## ⚙️ API Key Management

### View Keys
```bash
cat api_keys.json
```

### Generate New Key
```bash
curl -X POST http://127.0.0.1:5000/api/generate-key \

## 🛡️ Security Checklist

- ✅ API keys required for forecast endpoints
- ✅ CORS enabled for cross-origin requests
- ✅ Keys stored in JSON file (upgrade to database in production)
- ✅ Request counting and tracking enabled
- ✅ Error handling for invalid requests

### For Production:
- [ ] Use HTTPS instead of HTTP
- [ ] Implement database for key storage
- [ ] Add rate limiting
- [ ] Use environment variables for configuration
- [ ] Implement request logging
- [ ] Set up monitoring and alerts

## 🧪 Testing the API

```bash
python test_api_production.py
```

Expected output:
```
✅ Health: PASSED
✅ Forecast: PASSED
✅ ARIMA: PASSED

✅ All tests passed! API is ready for deployment.
```

## 💡 Tips for App Developers

1. **Cache Results**: Store forecasts locally to reduce API calls
2. **Handle Errors**: Always check `status` field in response
3. **Set Timeouts**: Use 30-second request timeout
4. **Store Key Securely**: Use environment variables, not hardcoded
5. **Monitor Usage**: Track requests_count in api_keys.json

---

## 📞 Support

For issues or questions:
1. Check `DEPLOYMENT_GUIDE.md` for detailed information
2. Review API response for error messages
3. Test with `test_api_production.py`
4. Enable debug logging in `api_production.py`

---

## ✨ Next Steps

1. **Test Locally**: Use the examples above to verify the API
2. **Integrate into App**: Use the provided code samples
3. **Deploy to Production**: Follow `DEPLOYMENT_GUIDE.md`
4. **Monitor**: Track API usage and performance
