We check SpaceX's listed URL (https://github.com/r-spacex/SpaceX-API) once a day. History started when SpaceX was first checked, so new entries show fewer than 30 days.

SpaceX 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. SpaceX doesn't send CORS headers, so browsers block calls made directly from a web page. Call it from your server instead.
  3. If it works from one network but not another, check firewalls, VPNs and regional blocks.
  4. Check the provider's documentation, status page or social accounts for planned maintenance or a changed endpoint.

SpaceX API status FAQ

Is SpaceX API down right now?

SpaceX answered our last daily check (Oct 24, 2026, 12:25 UTC) in 522 ms with HTTP 200. This page also runs a live check from our server when you open it, so you can see whether SpaceX is responding at this moment.

How do you check whether SpaceX API is up?

Once a day our checker requests SpaceX's listed URL (https://github.com/r-spacex/SpaceX-API) 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.

What can I use if SpaceX API is down?

Free Science & Math APIs that were up at their last check include GBIF, Macrostrat, Chempirical. See the full list of SpaceX alternatives for a comparison.

Why does SpaceX API work for others but not for me?

A 429 response means you're being rate-limited. Slow down, cache responses, and respect any Retry-After header. SpaceX doesn't send CORS headers, so browsers block calls made directly from a web page. Call it from your server instead. If it works from one network but not another, check firewalls, VPNs and regional blocks.
