Rate Limiting & Performance

Implement appropriate rate limiting, exponential backoff, and circuit breaker patterns in your applications. Use connection pooling, request batching, and asynchronous processing for high-throughput scenarios. Monitor API response times and implement performance optimization strategies.

Error Handling & Resilience

Always check the success field and implement comprehensive error handling with retry logic, fallback mechanisms, and graceful degradation. Use structured logging, error tracking, and alerting systems for production monitoring and debugging.

Caching & Optimization

Implement intelligent caching strategies for frequently requested data, use CDN for global distribution, and optimize network requests. Consider local caching, distributed caching, and cache invalidation strategies for optimal performance.

Input Validation & Security

Validate all parameters before sending requests, implement input sanitization, and use secure coding practices. Implement authentication, authorization, and security headers for enterprise applications. Follow OWASP guidelines and security best practices.

Monitoring & Observability

Implement comprehensive monitoring, logging, and observability including metrics collection, distributed tracing, and performance monitoring. Use APM tools, log aggregation, and real-time alerting for production systems.
