Error Handling

Production Checklist

  • Retry logic with exponential backoff
  • Circuit breaker pattern
  • Request/response logging
  • Cost tracking per feature
  • Health checks and alerts

Monitoring Setup

Track: request count, error rate, latency P95/P99, cost per request, and cache hit rate.
