Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## Physician Directory + NPI Cross-Reference Healthcare M&A volume cleared $1B+ in 2025 across PE rollups (TUSK Practice Sales, Practice Transitions Group). DSO deal flow alone was 10+ practices/month in September 2025. Every one of those buyers needs the same thing: a clean physician contact list with NPI, specialty, primary practice address, license number, and a working email pattern. This actor returns that record on demand at per-call pricing. [![Apify Store](https://img.shields.io/badge/Apify-Store-blue)](https://apify.com/george.the.developer/physician-directory-npi) [![Pricing](https://img.shields.io/badge/Pricing-PAY_PER_EVENT-green)](https://apify.com/george.the.developer/physician-directory-npi) ### Why this exists Definitive Healthcare sells the physician directory market at $25,000-$100,000 per seat per year. That's the price umbrella for every healthcare-M&A team, PE rollup, MedSpa broker, and physician-recruitment firm that needs the same dataset. The NPI Registry has been free public data from CMS since 2007. Healthgrades, Vitals, and ZocDoc are public-web. State medical license boards are searchable in every US state. The data is there. Nobody has wired it into a single per-call API that returns one normalized record. This actor does that. NPI Registry as the spine. State medical license board cross-reference for live status verification. Email guess generator for outreach. One call, one record, $0.05-$0.25 per row depending on enrichment level. ### How it works ```` ``` /search?specialty=&state= /enrich?npi= | | v v +----------+----------+ +--------+----------+ | NPI Registry CMS | | NPI Registry CMS | | (public, free) | | (single lookup) | +----------+----------+ +--------+----------+ | | | normalized | normalized v v results[] npiRecord | | | v | +--------+----------+ | | CA Med Board | | | (search.dca.ca) | | | via VPS Go TLS | | +--------+----------+ | | | | license + status | v | +--------+----------+ | | Email Guesser | | | (6 patterns x 3 | | | domain seeds) | | +--------+----------+ v v +------+------+ +--------+--------+ | basic record | | enriched record | | $0.05/row | | $0.25/row | +-------------+ +-----------------+ ``` ```` ### Endpoints | Method | Path | Description | Charge | |--------|------|-------------|--------| | GET | `/` | Service info, pricing, source list | none | | GET | `/health` | Liveness check | none | | GET | `/search?specialty=&state=&city=&limit=` | Search NPI Registry, return basic records | $0.05 per result | | GET | `/enrich?npi=` | Single NPI -> full enrichment | $0.25 per record | | GET | `/enrich?name=&state=` | Name + state -> NPI lookup -> enrichment | $0.25 per record | | POST | `/enrich/bulk` body `{npis:[...]}` (max 25) | Bulk enrichment | $0.25 per record | ### Quick start ```bash ## Search by specialty + state curl -s "https://george-the-developer--physician-directory-npi.apify.actor/search?specialty=Cardiology&state=CA&limit=10" \ -H "Authorization: Bearer YOUR_APIFY_TOKEN" ## Enrich a single NPI curl -s "https://george-the-developer--physician-directory-npi.apify.actor/enrich?npi=1710071717" \ -H "Authorization: Bearer YOUR_APIFY_TOKEN" ## Bulk enrich (max 25 NPIs) curl -s -X POST "https://george-the-developer--physician-directory-npi.apify.actor/enrich/bulk" \ -H "Authorization: Bearer YOUR_APIFY_TOKEN" \ -H "Content-Type: application/json" \ -d '{"npis":["1710071717","1528076718","1962778159"]}' ```` ### Sample response ```json { "ok": true, "record": { "npi": "1710071717", "name": "ABDUL SATTAR ABBASI", "credentials": "MD", "specialty": "Internal Medicine, Cardiovascular Disease", "specialty_group": "Other", "taxonomy_code": "207RC0000X", "primary_address": { "street": "1045 ATLANTIC AVE, SUITE 912", "city": "LONG BEACH", "state": "CA", "zip": "908133408", "phone": "562-437-2801", "fax": "" }, "license": { "state": "CA", "license_number": "A24632", "status": "unknown", "note": "Cross-referenced from NPI taxonomy.

At $0.25/record, you can pull 100,000 enriched physician records for $25,000 once. That's the price umbrella this is sitting under. ### Use cases - **PE healthcare rollups** building target lists across states for cardiology, orthopedics, dermatology, primary care, dental practice acquisition - **MedSpa M\&A brokers** identifying medical directors and specialty practice owners for M\&A outreach - **Physician recruitment firms** building active-license verified provider lists by specialty + region - **Medical sales reps** prospecting providers in target specialties (device manufacturers, pharma, RCM) - **Healthcare research firms** academic and competitive-intel firms running provider-density analyses - **Provider credentialing teams** verifying NPI + license + practice address in one call ### Honest tradeoffs (v1) - **State license live status:** v1 wires CA Medical Board (search.dca.ca.gov) live cross-reference. CA-MBC sits behind an F5 WAF that intermittently blocks Chrome-fingerprinted requests. When the live check returns 0 rows, the actor falls back to the NPI Registry taxonomy license number with `status:"unknown"` and a note. FL, NY, TX coming in v2. - **Healthgrades / Vitals / ZocDoc:** deferred to v2. Healthgrades and Vitals require Cloudflare bypass, ZocDoc requires Datadome bypass. Adding them is the work for v2 once the v1 dataset proves the demand. - **Email guessing:** the 6 patterns generated are *unverified guesses*. The note on each guess says so. Pair them with my [Email Validator API](https://apify.com/george.the.developer/email-validator-api) for SMTP-grade verification before sending outreach. - **NPI Registry specialty filter:** the public CMS API does substring match on `taxonomy_description`. A search for "Cardiology" returns Cardiologist MDs (taxonomy `207RC0000X`) plus pharmacists with cardiology certs (`1835C0206X`). Filter by `taxonomy_code` prefix `207RC` for MD-only cardiologists. - **Org NPIs (NPI-2):** included in search but enrichment treats them as the legal entity. For physician-level outreach, filter by `enumeration_type:"NPI-1"`. ### Test-payload short-circuit Pass NPI `1234567890` or `0000000001` or `9999999999`, or name `John Doe Test`, and the actor returns `{ok:true, mocked:true}` with no charge. Use these for CI smoke tests without burning credit. ```bash curl -s "https://george-the-developer--physician-directory-npi.apify.actor/enrich?_test=true&npi=0000000001" \ -H "Authorization: Bearer YOUR_APIFY_TOKEN" ## {"ok":true,"mocked":true,"reason":"test-payload short-circuit, NPI Registry skipped"} ``` ### More from this developer - [Email Validator API](https://apify.com/george.the.developer/email-validator-api) — pair with email guesses for SMTP verification ($0.002 per check) - [Domain WHOIS Lookup](https://apify.com/george.the.developer/domain-whois-lookup) — pull practice domain registration ($0.005 per domain) - [Company Enrichment API](https://apify.com/george.the.developer/company-enrichment-api) — full company profile from a domain ($0.01 per company) - [Obituary Life-Insurance Lead Scraper](https://apify.com/george.the.developer/obituary-life-insurance-leads) — sister actor for final-expense insurance prospecting - [Funded Startup Tracker](https://apify.com/george.the.developer/funded-startup-tracker) — TC RSS + SEC EDGAR fusion for VC outreach - [ATS Hire-Trigger Intent Scraper](https://apify.com/george.the.developer/ats-hire-trigger-intent-scraper) — Greenhouse + Lever + Ashby intent signals - [Shopify DTC Brand Discovery](https://apify.com/george.the.developer/shopify-dtc-brand-discovery) — DTC brand finder + Klaviyo tech-stack detection Built by George The Developer.
