0x API not working for you?

  1. A 429 response means you're being rate-limited. Slow down, cache responses, and respect any Retry-After header.
  2. If it works from one network but not another, check firewalls, VPNs and regional blocks.
  3. Check the provider's documentation, status page or social accounts for planned maintenance or a changed endpoint.

0x API status FAQ

Is 0x API down right now?

0x answered our last daily check (Oct 24, 2026, 12:25 UTC) in 2077 ms with HTTP 200. This page also runs a live check from our server when you open it, so you can see whether 0x is responding at this moment.

How do you check whether 0x API is up?

Once a day our checker requests 0x's listed URL (https://docs.0x.org/) and records whether it answers within 15 seconds. Answers like 401 (needs a key), 403 (blocks bots) or 429 (rate-limited) count as up, because the server responded. The listed URL is often the documentation page, so an API endpoint can occasionally fail while its docs stay up.

Check the provider's documentation, status page or social accounts for planned maintenance or a changed endpoint.
