How this service works
Search US clinicians by location and specialty using the CMS NPPES NPI Registry. Returns normalized provider records: npi, name, primary taxonomy, practice address, licenses. board_certified is always null (NPPES does not include ABMS certification).
Output
A list of normalized US clinician records from the CMS NPPES NPI Registry, each containing the provider's NPI number, full name, primary taxonomy (specialty), practice address, and license information. The board_certified field is always null since NPPES does not include ABMS board certification data.
Example use cases
Example prompt
“Can you find me cardiologists practicing in Chicago, IL using the NPI registry — I need their names, NPI numbers, and practice addresses?”
Technical details
Endpoint
POSThttps://doc-finder.adeel-094.workers.dev/v1/doctors/search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to find US clinicians by geographic location and/or medical specialty, retrieve NPI numbers, or look up practice addresses and license information sourced directly from the official CMS NPPES registry. Prefer this over generic physician finder services when NPI accuracy and official CMS data provenance are important. Not suitable if you need board certification status (ABMS data is not included).
Side effects
- No matching providers found for given location or specialty — returns empty results
- Invalid or unsupported specialty/taxonomy string — may return empty or unrelated results
- CMS NPPES upstream API unavailability — service may return error or timeout
- Missing required search parameters — returns validation error
- Rate limiting or micropayment failure — returns 402 payment required
