Using the API

Rate limits and 429s

The default limit, the headers on every response, and how to back off correctly.

Keys are limited to 60 requests per minute by default. A higher limit can be set on a key, so tell us if you need one.

Headers

Every response carries the current state, so you can pace yourself without guessing:

text
X-RateLimit-Limit: 60
X-RateLimit-Remaining: 58
X-RateLimit-Reset: 1717619400

When you exceed it

You get 429 Too Many Requests with a Retry-After header in seconds. Honour it. Retrying immediately extends the window rather than shortening it.

Rate limits are not credits

A 429 costs no credit. It means you are sending too fast, not that you have run out.

Limits are per account rather than per key, and are listed with the current plans.
