### Rate limiting

The Cortex API limits requests to 1000 per minute per client. The body size of any given request has a maximum of 2MB.
If you attempt too many requests in a short period, a `429` error will be returned with a `Retry-After` header. If you are hitting rate limits frequently, please contact your Cortex Customer Success Manager to discuss your use case.

<Info>
  API rate limits are subject to change. Customers will be notified of any changes made to the rate limits.
