NPPES 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 calls fail only in the browser with a CORS error, NPPES may not allow cross-origin requests. 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.

How do you check whether NPPES API is up?

Once a day our checker requests NPPES's listed URL (https://npiregistry.cms.hhs.gov/registry/help-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.

If calls fail only in the browser with a CORS error, NPPES may not allow cross-origin requests. Call it from your server instead. If it works from one network but not another, check firewalls, VPNs and regional blocks.
