How to call it
A starting template for CircleCI. Replace ENDPOINT with the path from the official documentation, which we link above rather than guess at.
# Requires an API key. Check the docs for whether it goes in a header or a query parameter.
curl -s "https://circleci.com/ENDPOINT" \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Accept: application/json"This API does not send CORS headers, so a browser will block a direct call from your front end. Call it from your server, or put a small proxy in front of it.

CircleCI — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is CircleCI free to use?
CircleCI is listed in our free catalogue, but it requires an API key, so you will need to register before your first call. Providers frequently reserve higher limits and commercial use for paid plans.
Does CircleCI need an API key?
Yes. CircleCI authenticates with an API key. Keep it server-side rather than in browser code, because anything in your frontend bundle is readable by anyone who opens developer tools.
Can I call CircleCI from browser JavaScript?
Not directly. CircleCI did not return CORS headers when we checked, so the browser will block your page from reading the response even though the request itself succeeds. Call it from a server, or put a small proxy in front of it.
Is CircleCI still working?
Yes, as of 2026-09-18. Our automated check reached CircleCI and recorded a 100% reliability score with a median response time of 439 ms. We re-check on a schedule, and this page updates with the result.
Is CircleCI available over HTTPS?
Yes. CircleCI serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
