Errors

rate_limited

429 Rate limited. Too many requests.

StatusCodeRetry?
429 Rate limitedrate_limitedYes, after waiting

What it means

Too many requests. A key may make 120 requests a minute. The RateLimit header says how many are left, and Retry-After how long to wait.

Common causes

  • A loop sending requests without waiting.
  • Several programs sharing one key.

What to do

Wait the number of seconds in retry_after, then try again.

Can I retry it?

Yes, after waiting. Wait the seconds in retry_after (or the Retry-After header) when the answer has them, otherwise back off from a second or two. With the same Idempotency-Key, a retried send never sends twice.

Branch on code, which never changes. message and hint are written for people and may be reworded. Quote request_id when you write to support.
