How to call it

A starting template for Countly. Replace ENDPOINT with the path from the official documentation, which we link above rather than guess at.

# No authentication required.
curl -s "https://api.count.ly/ENDPOINT" \
  -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.

This API is served over plain HTTP. Browsers block HTTP requests made from an HTTPS page, so you will need a server-side call.

Where this listing comes from

Countly — common questions

Answered from what our own scheduled checks found, not from the provider's marketing.

Is Countly free to use?

Countly is listed in our free catalogue and required no credential when we called it. It needs no authentication at all, so you can send a request without signing up. Free tiers can still carry rate limits or non-commercial terms, so check the provider's own terms before shipping.

Does Countly need an API key?

No. We called Countly on 2026-09-18 with no key, no token and no Authorization header, and it responded. That is what puts it in our no-key collection.

Can I call Countly from browser JavaScript?

Not directly. Countly 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 Countly still working?

Yes, as of 2026-09-18. Our automated check reached Countly and recorded a 100% reliability score with a median response time of 1789 ms. We re-check on a schedule, and this page updates with the result.

Is Countly available over HTTPS?

No. Countly was only reachable over plain HTTP when we checked. Browsers block HTTP requests made from an HTTPS page, so this will fail in production unless you call it from a server instead.
