Rate limits

Per-key limits, the headers we return, and how to back off.

Each API key has a per-minute request budget. Every response advertises your current standing:

HeaderMeaning
X-RateLimit-LimitRequests allowed per minute
X-RateLimit-RemainingRequests left in the current window
Retry-AfterSeconds to wait (sent on 429)

When you exceed the budget you get 429 with code: rate_limited and a Retry-After header. Back off for that many seconds, then retry.

The SDKs handle this for you

The official SDKs read these headers and retry with backoff automatically.
