OpenHolidays API — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is OpenHolidays API free to use?
OpenHolidays API is listed in our free catalogue and required no credential when we called it. It needs no authentication at all, so you can send a request without signing up. Free tiers can still carry rate limits or non-commercial terms, so check the provider's own terms before shipping.
Does OpenHolidays API need an API key?
No. We called OpenHolidays API on 2026-09-18 with no key, no token and no Authorization header, and it responded. That is what puts it in our no-key collection.
Can I call OpenHolidays API from browser JavaScript?
Not directly. OpenHolidays 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 OpenHolidays API still working?
Yes, as of 2026-09-18. Our automated check reached OpenHolidays API and recorded a 100% reliability score with a median response time of 2781 ms. We re-check on a schedule, and this page updates with the result.
Is OpenHolidays API available over HTTPS?
Yes. OpenHolidays API serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
