NPPES NPI Registry
The NPPES API provides a real-time alternative to accessing NPPES public data, allowing users to retrieve detailed information about healthcare providers using their National Provider Identifier (NPI). Unlike the traditional method of batch downloads, this API facilitates faster and more efficient queries for provider data. The API currently operates with version 2.1, enhancing accessibility and ease of use.

NPPES NPI Registry — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is NPPES NPI Registry free to use?
NPPES NPI Registry is listed in our free catalogue, but it requires some form of authentication, so you will need to register before your first call. Providers frequently reserve higher limits and commercial use for paid plans.
Does NPPES NPI Registry need an API key?
NPPES NPI Registry requires some form of authentication. Check the provider's documentation for which scheme it expects.
Can I call NPPES NPI Registry from browser JavaScript?
Not directly. NPPES NPI Registry did not return CORS headers when we checked, so the browser will block your page from reading the response even though the request itself succeeds. Call it from a server, or put a small proxy in front of it.
Is NPPES NPI Registry still working?
Yes, as of 2026-09-18. Our automated check reached NPPES NPI Registry and recorded a 100% reliability score with a median response time of 1294 ms. We re-check on a schedule, and this page updates with the result.
Is NPPES NPI Registry available over HTTPS?
Yes. NPPES NPI Registry serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
