0x — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is 0x free to use?
0x 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 0x need an API key?
No. We called 0x 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 0x from browser JavaScript?
Yes. 0x 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 0x still working?
Not at our last check on 2026-09-18. 0x did not respond successfully, which is why it is marked as down here. This may be temporary; we re-check on a schedule and the badge above reflects the most recent run.
Is 0x available over HTTPS?
Yes. 0x serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
