Open VSX 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.
