Rate limits

Clerk rate limits certain endpoints to help protect users against brute-force attacks or to stop abuse of Clerk's platform. Rate limiting is based on IP addresses.


If you receive a 429 error code, that means your IP address has been rate limited. All subsequent requests to that specific endpoint coming from your IP address will be blocked for a given amount of time.

Requests that have been rate limited, will receive the Retry-After response header, which contains the number of seconds after which the block expires.
