Usage and limits

API Usage

Each eligible plan has an allotted number of Admin API requests, with higher-tier plans offering increased request limits. This gives you more flexibility as your needs grow.

Plans

• Business - 5,000 requests/month

• Enterprise and Circle Plus - 30,000 requests/month

• Circle Plus Platform - 250,000 requests/month

Note that Zapier usage does not count towards these limits.

You can monitor your usage by going to the Developers tab in your admin area.

If you exceed your limits over the next few months, don’t worry: we won’t be enforcing our API limits until January 1, 2025 so you have time to establish a baseline and upgrade your plan if needed.

Rate limits

To prevent attacks and/or abuses, there's a rate limiting mechanism in place on all of Circle's APIs. The limit is 2000 request per 5 minutes per IP. That number can change at any time. Is important to freeze that this limit is high when we look at other API providers. A good practice is, as soon as you get a 429 (Too Many Requests), you put your script to sleep and don't keep sending requests.

FAQ

Why isn't my API usage count updated immediately after making API requests?

API usage counts are not updated in real-time due to backend processing. We cache the usage count for one minute on our side, so you can expect the count to be updated ~5min after performing that call.

Which response codes are considered as part of my limit?

We consider API requests with the following response codes for updating the API usage count:

200: OK 201: Created 204: No Content 400: Bad Request 401: Unauthorized 403: Forbidden 404: Not Found 405: Method Not Allowed 422: Unprocessable Entity 429: Too Many Requests

Any 500 or other internal server errors are not computed and will not count as a request.
