NPPES NPI RegistryFree REST API
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.
FreeAPI Smart Gateway Supported (Recommended)
Zero account setup or API key registration needed. Call directly through FreeAPI Smart Edge Gateway with in-memory cache, automatic CORS support, and normalized JSON output.
Live Test Console & 3D Assistant
Launch 3D studio to inspect query parameters, authentication headers, or test with your personal developer key.
