Yahoo Finance API — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Yahoo Finance API free to use?
Yahoo Finance 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 Yahoo Finance API need an API key?
Yahoo Finance API requires some form of authentication. Check the provider's documentation for which scheme it expects.
Can I call Yahoo Finance API from browser JavaScript?
Not directly. Yahoo Finance 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 Yahoo Finance API still working?
Yes, as of 2026-09-18. Our automated check reached Yahoo Finance API and recorded a 100% reliability score with a median response time of 873 ms. We re-check on a schedule, and this page updates with the result.
Is Yahoo Finance API available over HTTPS?
Yes. Yahoo Finance API serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
