NPI Scraper API

The Piloterr NPI Scraper API lets you extract public data from NPI as clean, structured JSON — no proxies, headless browsers or HTML parsing to maintain. Endpoints available in production:

NPI Provider API — Fetch one NPPES provider or organization by 10-digit NPI or provider-view URL, including addresses and taxonomies.
NPI Search API — Search the NPPES NPI registry by person name, organization, or 10-digit NPI.

Use it for price monitoring, assortment tracking, competitor analysis, product research or catalog enrichment.

Endpoint	Path	Credits	What you get
NPI Provider API	`/v2/npi/provider`	1	Fetch one NPPES provider or organization by 10-digit NPI or provider-view URL, including addresses and taxonomies.
NPI Search API	`/v2/npi/search`	1	Search the NPPES NPI registry by person name, organization, or 10-digit NPI. With NPI-2, a text query is the organization name. total_results is null, and next is set only when the page is full.

How it works

Create a free Piloterr account and copy your API key from the dashboard.
Send a GET (or POST) request to https://api.piloterr.com/v2/... with the header x-api-key: YOUR_API_KEY.
Receive structured JSON — Piloterr handles rendering, proxies, retries and parsing.

export PILOTERR_API_KEY="your-api-key"
pip install requests        # Python
# TypeScript: Node.js 18+ (native fetch), run with `npx tsx file.ts`

Every endpoint accepts both GET (query string) and POST (JSON body with the same fields).

NPI Provider API

Fetch one NPPES provider or organization by 10-digit NPI or provider-view URL, including addresses and taxonomies.

Request parameters

Parameter	Type	Required	Description
`query`	string	✅	Required. 10-digit NPI, example 1972813608, or a provider-view URL such as https://npiregistry.cms.hhs.gov/provider-view/1972813608.

Python example

import json
import os
import requests

response = requests.get(
    "https://api.piloterr.com/v2/npi/provider",
    headers={"x-api-key": os.environ["PILOTERR_API_KEY"]},

        "query": "https://npiregistry.cms.hhs.gov/provider-view/1972813608",
    },
    timeout=120,
)
response.raise_for_status()
data = response.json()

print(json.dumps(data, indent=2, ensure_ascii=False)[:2000])

Structured JSON — stable, documented fields instead of brittle HTML selectors.
Pay per request — transparent credit cost per endpoint, failed requests are retried for you.
One API key, hundreds of sources — NPI plus many other e-commerce, search and company data endpoints in the Piloterr library.
Any language — plain HTTPS + JSON, with examples for Python, TypeScript, cURL, PHP, C#, Go, Java, Ruby and Node.js.

FAQ

Is it legal to scrape NPI?

Collecting publicly available data is generally allowed in many jurisdictions, but rules depend on your country, the data you collect and how you use it. Avoid personal data unless you have a lawful basis, respect the website's terms where they apply, and get legal advice for your specific use case. This is not legal advice.

Do I need proxies or a headless browser?

No. Piloterr handles rendering, proxy rotation and retries on its side. You only send an HTTPS request with your x-api-key header and receive JSON.

How much does a request cost?

Credits per call: /v2/npi/provider 1, /v2/npi/search 1. See the Piloterr website for plans.

What data does the NPI API return?

Each endpoint returns structured JSON: NPI Provider — npi, sex, url, city, name, phone; NPI Search — results[], results[].npi, results[].url, results[].city, results[].name, results[].phone.

How do I paginate NPI results?

Use the page parameter and keep requesting while the response indicates more results.

Which languages are supported?

Any language that can make an HTTP request. This README shows Python and TypeScript; the examples/ folder contains cURL, PHP, C#, Go, Java, Ruby and Node.js.
