How to call it

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

# Authentication requirement is unconfirmed. Check the documentation before relying on this.
curl -s "https://github.com/ENDPOINT" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -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.

Kmail API — common questions

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

Is Kmail API free to use?

Kmail API is listed in our free catalogue, but it requires some form of authentication, so you will need to register before your first call. Providers frequently reserve higher limits and commercial use for paid plans.

Does Kmail API need an API key?

Kmail API requires some form of authentication. Check the provider's documentation for which scheme it expects.

Can I call Kmail API from browser JavaScript?

Not directly. Kmail API 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 Kmail API still working?

Yes, as of 2026-09-18. Our automated check reached Kmail API and recorded a 100% reliability score with a median response time of 910 ms. We re-check on a schedule, and this page updates with the result.

Is Kmail API available over HTTPS?

Yes. Kmail API serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
