NPI reference

One canonical record per National Provider Identifier

Every /npi/<npi> page resolves a single 10-digit NPI across the federal source graph and renders it server-side with field-level provenance — the source name and snapshot date behind every claim. Stable, permanent URLs built for citation by people, search engines, and AI agents. Each record is also available as JSON at /api/v1/npi/<npi>.

Don't have an NPI to hand? Look one up by name or specialty, or browse the provider directory.
