Aletheia — common questions

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

Is Aletheia free to use?

Aletheia 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 Aletheia need an API key?

Yes. Aletheia 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 Aletheia from browser JavaScript?

Yes. Aletheia 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 Aletheia still working?

Yes, as of 2026-09-18. Our automated check reached Aletheia and recorded a 100% reliability score with a median response time of 566 ms. We re-check on a schedule, and this page updates with the result.

Is Aletheia available over HTTPS?

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