How to document API rate limits so small teams can plan around them

API rate limit documentation should tell developers the limit, the window, the scope, the headers, and what to do after a 429 response.

Small teams often document rate limits as one number, such as “100 requests per minute.” That is not enough. Developers need to know whether the limit is per API key, user, workspace, endpoint, IP address, or plan. They also need to know whether reads and writes share the same budget and whether burst behavior is allowed.

A useful rate-limit section includes examples. Show a normal response header, a 429 response body, retry-after behavior, and a safe retry pattern. If the API has pagination, batch endpoints, webhooks, or export jobs that reduce request volume, link those alternatives near the limit.

Plan boundaries should be explicit. If higher plans get larger limits, say whether the increase is automatic, request-based, or tied to a fair-use review. If limits can change during incidents or abuse prevention, document the policy boundary without exposing security rules.

The goal is not to invite maximum usage. The goal is to let developers design stable integrations that fail politely when the limit is reached.
