Aare.guru API — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Aare.guru API free to use?
Aare.guru 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 Aare.guru API need an API key?
Aare.guru API requires some form of authentication. Check the provider's documentation for which scheme it expects.
Can I call Aare.guru API from browser JavaScript?
Not directly. Aare.guru 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 Aare.guru API still working?
Yes, as of 2026-09-18. Our automated check reached Aare.guru API and recorded a 100% reliability score with a median response time of 1048 ms. We re-check on a schedule, and this page updates with the result.
Is Aare.guru API available over HTTPS?
Yes. Aare.guru API serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
