US healthcare provider lookup (NPPES NPI Registry). Every US doctor, nurse, dentist, hospital, lab, pharmacy has an NPI — this returns the canonical record. Lookup by 10-digit NPI for a precise match, or by firstName + lastName + state for fuzzy search. Each record includes name + credentials, status, enumeration date, primary + secondary specialty taxonomies (with state license numbers), practice + mailing addresses, phone, and any cross-issuer identifiers (Medicaid, Medicare, etc.). Public-domain CMS data, free. For all three NPI datasets merged (identity + industry payments + Medicare billing) in one call, see /api/health/provider-profile.
