How to consume rate-limited APIs safely: read RateLimit headers, handle 429s with backoff, and monitor throttled dependencies before they break your app.
What 4xx HTTP client errors mean — 400, 401, 403, 404, 405, 408, 410, 429 — their causes, how they differ from 5xx, and how to monitor and alert on them.
Monitor API rate limits and 429 throttling errors. Track quota usage, retry-after headers, and avoid surprise outages from third-party caps.
