CMS NPI Healthcare Provider Registry Tracker – NPPES Provider API

A CMS NPI Registry API wrapper and healthcare-provider data feed that pulls U.S. providers from the official NPPES registry and normalizes each into a clean record: NPI, name (individual or organization), primary taxonomy/specialty, practice address, license state, phone and status. Use it to build a provider-directory dataset, a healthcare sales-intelligence feed, a credentialing lookup, or referral-network tooling.

Who uses it

Health-tech and provider-directory products, medical-device and pharma sales teams building territory lists, credentialing and payer-enrollment teams, and healthcare data vendors.

Why this is worth charging for

The NPI registry is the authoritative directory of U.S. providers, but its API returns deeply nested basic/address/taxonomy objects and caps skip at 1,000. This actor picks the practice-location address and primary taxonomy, handles enumeration type (individual vs organization), and delivers a clean, queryable provider feed by specialty, name or geography.

Output

Each dataset item is one normalized record:

{
  "npi": "1234567890",
  "enumerationType": "NPI-1",
  "name": "JOHN SMITH",
  "credential": "MD",
  "primaryTaxonomy": "Internal Medicine",
  "taxonomyCode": "207R00000X",
  "licenseState": "MA",
  "addressCity": "BOSTON",
  "addressState": "MA",
  "addressPostal": "02118",
  "phone": "617-555-1212",
  "status": "A",
  "url": "https://npiregistry.cms.hhs.gov/provider-view/1234567890",
  "source": "CMS NPPES"
}

Input

Field	Description
enumerationType	Restrict to individual or organizational providers.
taxonomyDescription	Specialty description, e.g. 'Cardiology' or 'Pharmacy'.
organizationName	Organization name search (supports trailing wildcard).
firstName	Individual provider first name.
lastName	Individual provider last name.
city	Practice city.
state	Practice state.
postalCode	Practice ZIP (supports wildcard).
npi	Look up one specific NPI number.
pageSize	Results per page (NPPES max 200).
maxPagesToScan	Pages per run (NPPES caps total skip at 1,000).
onlyNewSinceLastRun	Recommended for schedules — skips records already returned by a previous run using persisted state, so you're only charged for genuinely new items.
maxItems	Stop after this many normalized records.

Pricing (Pay-Per-Event)

• query — $0.02, charged once per run for the API query/poll.
• provider-record — $0.01 per normalized record pushed. This is the primary event.
• apify-actor-start (Apify-managed) — covers baseline compute per run.

A specialty+geography pull returns up to ~1,000 providers per run for a few dollars. Narrow with city/state/taxonomy to build precise territory lists cheaply.

Source & reliability

Data comes from the official npiregistry.cms.hhs.gov NPPES API. Practice-location address and primary taxonomy are selected automatically. No key or proxies required. Run npm test for the offline self-test covering the normalizer, including edge cases and missing-field handling.

FAQ

Is there an API for the NPI registry?

Yes — this actor wraps the official NPPES API and returns clean, flattened provider records via the Apify API, webhook or export.

Can I build a specialty list for a state?

Yes. Set taxonomyDescription and state (NPPES caps results at 1,200 per query; narrow by city/ZIP for more coverage).

Need the rest of the record on these companies?

This actor returns one source. KYB Company Data Enrichment takes a company name and returns what the public record says about it across up to nine sources — state business registries, UCC lien filings, tax warrants and WARN layoff notices, the FMCSA motor-carrier census, the CMS NPI Registry, USAspending federal awards, EPA ECHO compliance, SEC EDGAR filings and CourtListener federal dockets.

Every enriched field carries its source and its match confidence. Only matches above the accept threshold are merged — anything weaker is surfaced as a suggestion and never folded into the record, because a false join is worse than returning nothing.
