🔒 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
