## AI overview

A practical guide to designing resilient APIs in distributed systems. It covers fail-fast validation, graceful degradation, idempotency for safe retries, and bounded retry policies using exponential backoff, jitter, attempt limits, and total time budgets.

## Source excerpt

Resilience is failing in controlled ways rather than not failing. Validate and fail fast at the boundary, degrade gracefully by serving cached or reduced responses, require an idempotency key for side-effecting operations, and bound retries with exponential backoff, jitter, an attempt cap, and a total time budget. Unbounded retries amplify outages.
