Discuss API error handling and retry mechanisms.
**Why Robust Handling**: APIs fail—transient (5xx, timeout) vs. permanent (4xx). Retrying 400 wastes time; not retrying 503 causes false failures. **Strategy**: Exponential backoff with jitter to avoid thundering herd; cap retries (3-5); circuit breaker after consecutive failures. Idempotency keys for POST/PUT. **Cost**: Retries add latency and load; distinguish retriable vs. non-retriable. Log request IDs for correlation....
