## Pricing
Pay per usage
This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

## What's an Apify Actor?
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
## NPI Provider Lookup
Look up US healthcare providers and organizations from the CMS NPPES NPI registry. Pass an NPI number, a name, a taxonomy, or a city and state, and get back clean normalized records instead of the raw nested registry JSON.
It runs as a standby API (instant HTTP responses) and also as a normal batch actor that writes to a dataset.
```mermaid
flowchart LR
A["Request
NPI / name / taxonomy / state"] --> B{mode}
B -->|provider| C["NPPES by NPI number"]
B -->|search| D["NPPES individual search"]
B -->|org| E["NPPES organization search"]
C --> F["Flatten
taxonomy + address + contact"]
D --> F
E --> F
F --> G[("Dataset
normalized providers")]
````
### What it does
- Resolves a single provider by 10-digit NPI number.
- Searches individual providers by last name, first name, taxonomy, city, and state.
- Searches organizations (NPI-2) by name and location.
- Flattens the registry payload into one row per provider with primary taxonomy, license, practice address, and phone.
Data comes straight from the public CMS NPPES registry API. No key, no proxy, no browser.
### Endpoints (standby mode)
| Method | Path | Query params | Returns |
| --- | --- | --- | --- |
| GET | `/provider` | `npi` | single normalized provider |
| GET | `/search` | `last_name`, `first_name`, `state`, `taxonomy`, `city`, `limit` | individual providers |
| GET | `/org` | `name`, `state`, `city`, `taxonomy`, `limit` | organizations |
| GET | `/` or `/health` | none | service info |
### Pricing (pay per event)
| Event | Price (USD) | When |
| --- | --- | --- |
| `actor-start` | $0.25 | once per paid batch run |
| `provider-record` | $0.01 | per normalized provider returned |
| `enriched-provider` | $0.02 | per provider that has full taxonomy + address + contact |
Health probe values like `test`, `ping`, `example`, or a placeholder NPI such as `1234567890` return a mock and are never charged.
### Example requests
Single provider by NPI:
```bash
curl "https:///provider?npi=1104130236"
```
Search individuals:
```bash
curl "https:///search?last_name=smith&state=CA&taxonomy=Family%20Medicine&limit=10"
```
Search organizations:
```bash
curl "https:///org?name=hospital&state=NY&limit=10"
```
Batch run (input JSON):
```json
{ "mode": "search", "last_name": "smith", "state": "CA", "limit": 25 }
```
### Output schema
Each provider row:
```json
{
"npi": "1104130236",
"type": "individual",
"first_name": "SHELLEY",
"last_name": "AKEY",
"organization_name": null,
"credential": "RN, NNP",
"status": "A",
"primary_taxonomy": "Nurse Practitioner, Neonatal",
"taxonomy_code": "363LN0000X",
"license": "AP3827",
"enumeration_date": "2010-07-30",
"last_updated": "2025-03-03",
"practice_address": {
"address_1": "1919 E THOMAS RD",
"city": "PHOENIX",
"state": "AZ",
"postal_code": "850167710"
},
"phone": "602-933-6345",
"fax": null,
"fetched_at": "2026-06-10T00:00:00.000Z"
}
```
For organizations, `type` is `organization`, `organization_name` is populated, and `first_name` / `last_name` are null.
### Flow

### Privacy note
This actor reads only the CMS NPPES NPI registry, which is a public provider directory published by the Centers for Medicare and Medicaid Services. It contains business and licensing details about healthcare providers and organizations. There is no patient data, no PHI, and no treatment information involved.

const run = await client.actor("george.the.developer/npi-provider-lookup").call(input);
// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {

run = client.actor("george.the.developer/npi-provider-lookup").call(run_input=run_input)
# Fetch and print Actor results from the run's dataset (if there are any)
print("💾 Check your data here: https://console.apify.com/storage/datasets/" + run["defaultDatasetId"])
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
print(item)
