Add Key Validation Health Checks +**Recommendation**: Periodic validation of stored keys +```python +@periodic_task(run_every=timedelta(hours=24)) +def validate_stored_keys(): + # Check if keys are still valid + # Notify users of expiring keys +``` + +#### 5. Implement Provider-Specific Error Handling +**Recommendation**: Better error messages per provider +```python +class ProviderErrorHandler: + def handle_rate_limit(self, provider) + def handle_invalid_key(self, provider) + def handle_quota_exceeded(self, provider) +``` + +### Low Priority + +#### 6. Add Analytics Dashboard +**Recommendation**: Visual dashboard for key usage +- Requests per provider +- Token usage trends +- Cost estimation +- Error rates + +#### 7.
