Billing & revenue cycle

An NPI lookup API for billing and RCM teams

Resolve provider and organization NPIs with one HTTP call and a stable JSON contract. Skip one-off NPPES parsing in every service—use the same signup, API keys, and docs path as the rest of the product.

Same funnel as the homepage: sign up → create a key in the dashboard → call GET /api/v1/npi/{npi} with Authorization: Bearer.

Why this page exists

Billing and RCM products repeatedly need registry-backed answers: is this NPI active, is it an individual or organization, and what taxonomy codes apply? Raw NPPES responses work, but they push parsing and edge cases into every app that touches an NPI field.

Health Provider API returns normalized provider JSON from the public NPI Registry with bearer keys, caching, and documented errors—so your billing stack can treat NPI resolution like any other internal HTTP dependency.

What you ship first

  1. Create a free account and generate an API key.
  2. Follow the copy-ready examples on the docs quickstart (curl, JavaScript, Node, Python, Go).
  3. Import the OpenAPI spec or Postman collection and wire your first lookup in your staging environment.

Minimal request

One lookup pattern for billing services

Use the same endpoint your engineers already test against in docs—swap in a real key from the dashboard.

Example curl
Replace the placeholder with your API key after sign-up.
curl -sS -H "Authorization: Bearer YOUR_API_KEY" "https://healthproviderapi.com/api/v1/npi/1003000126"
Keys and quotas
Account-level API keys, usage metering, and upgrade path when volumes grow.
Documented errors
Stable HTTP status and error codes for invalid NPI, auth, quota, and upstream issues.
