How this service works
CMS NPPES NPI Registry search: NPI number, name, credential, status, taxonomy (specialty code and description) and practice location. Matches can be fuzzy; the registry decides the match. Up to 10 records per call.
Output

Example use cases
Verify physician NPI before billing
“I need to verify the NPI number and active status for Dr. Sarah Williams, a cardiologist — can you search the NPPES registry for her and return her taxonomy and practice location?”
Find local providers by specialty state
“Look up up to 10 nurse practitioners with the last name 'Garcia' in California and give me their NPI numbers, credentials, and practice addresses.”
Credential check for new hire
“We're onboarding a new provider named Dr. Robert Chen — can you search the NPI registry to confirm his credentials, specialty taxonomy, and that his record shows as active?”
Technical details
Endpoint
GEThttps://api.healthtravel-api.workers.dev/api/health/npi-provider-registry?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to look up a US healthcare provider's NPI number, verify their credentials and active status, or retrieve their specialty taxonomy and practice location from the official CMS NPPES database. Prefer this over general web search when you need structured, authoritative registry data for billing, credentialing, or compliance purposes.
Side effects
- No results returned if last name is too short (under 2 characters) or contains invalid characters
- Fuzzy matching may return unrelated providers with similar names
- Up to 10 records cap may miss the target if many providers share a last name
- Invalid state code returns no results or an error
- Registry may have stale or incomplete data for some providers
