How this service works

Look up a US individual health care provider by provider number, or by name and state.

Output

Returns a JSON object with a total count and an array of matching provider records. Each record includes the provider's NPI, active status, name, credential (e.g. MD, DO, NP), specialties (with taxonomy code, description, license number and state), registration and last-updated dates, mailing address, and practice address with phone numbers.

Example use cases

Verify physician credentials before referral

“I need to verify Dr. Sarah Johnson's credentials — she's a physician in Texas. Can you find her NPI, specialty, and license number using her last name Johnson and state TX?”

Find practice address for a known NPI

“Look up NPI 1245319599 for me and return the doctor's full practice address and phone number so I can direct a patient there.”

Search for a specialist by name and location

“Find me up to 5 cardiologists with the last name Patel in California — I need their NPI numbers, specialties, and whether they're currently active.”

Technical details

Endpoint

When to prefer

Use this endpoint when you need authoritative US healthcare provider data sourced from the NPPES registry — especially for verifying NPI numbers, checking provider credentials and specialties, or retrieving official practice and mailing addresses. Prefer this over general web search or person-enrichment endpoints when the subject is a licensed US health professional and you need structured, license-level detail. It accepts either a direct NPI lookup (fast, deterministic) or a name+state search (broader discovery).

Side effects

No matching provider found — returns empty providers array with total: 0
Invalid NPI format (must be exactly 10 digits) — likely returns an error or empty result
Both NPI and last name provided simultaneously — API documentation says never provide both; may return an error
Missing required pairing (last name without state) — state is required when searching by name
State code not recognized — must be a valid two-letter US code
Payment failure via x402 — call not executed if USDC payment on Base cannot be settled
