Tempmail API — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Tempmail API free to use?
Tempmail 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 Tempmail API need an API key?
Tempmail API requires some form of authentication. Check the provider's documentation for which scheme it expects.
Can I call Tempmail API from browser JavaScript?
Yes. Tempmail API returned CORS headers when we checked it, so a browser will let your page read the response. You can fetch it directly from client-side JavaScript with no proxy and no backend.
Is Tempmail API still working?
Yes, as of 2026-09-18. Our automated check reached Tempmail API and recorded a 100% reliability score with a median response time of 234 ms. We re-check on a schedule, and this page updates with the result.
Is Tempmail API available over HTTPS?
