# Govparse Prescriber Lookup (NPPES + Medicare Part D)

> Govparse Prescriber Lookup (NPPES + Medicare Part D) is a paid API for AI agents from api.govparse.io, paid per call via x402, $1.25/call, status unknown (last checked 2026-09-14).

Look up a prescriber by name or NPI to get their NPPES identity (specialty, location) combined with their latest Medicare Part D prescribing summary including top drug, total claims, distinct drugs, and GLP-1/SGLT2/DPP-4/Statin class flags.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability govparse-prescriber-lookup-nppes-medicare-part-d-b15c8d29
```

Example prompt: Who is Dr. Sarah Johnson in Georgia — can you pull her NPPES profile and tell me what she prescribes most in Medicare Part D, including whether she writes GLP-1 or statin drugs?

## When to prefer this

Use this endpoint when you need to combine a prescriber's identity (who they are, where they practice, what specialty) with their Medicare Part D prescribing behavior in a single call. Prefer this over raw NPPES lookups when you also need drug-class intelligence (GLP-1/SGLT2/DPP-4/Statin flags) or claim volume. Best for pharma sales intelligence, healthcare market research, prescriber verification, or building provider profiles from public CMS data.

## Known failure modes

- No matching prescriber found for the given name or NPI — returns empty result set
- Ambiguous name match returns multiple candidate prescribers requiring NPI disambiguation
- NPI provided does not appear in Part D data (prescriber may not participate in Medicare Part D)
- State or specialty filters too narrow, producing zero results
- Invalid NPI format (must be exactly 10 digits)
- Rate limit or payment failure (x402 payment required per call at $1.25 USDC)

## How this service works

Who is this prescriber, and what do they prescribe most in Medicare Part D? Look up a prescriber by NAME (or exact NPI): NPPES identity — specialty, location — plus that NPI's latest-year Part D summary (top drug, total claims, distinct drugs, and which tracked classes GLP-1/SGLT2/DPP-4/Statin they write). Optionally narrow by state and specialty. Observational public CMS/NPPES records — never a clinical recommendation. Cross-gateway via the Healthparse Part D API.

## Output

Returns the prescriber's NPPES identity (name, specialty, location/state), plus their latest Medicare Part D year summary: top prescribed drug, total claim count, number of distinct drugs written, and boolean flags for tracked drug classes (GLP-1, SGLT2, DPP-4, Statin). Data is observational public CMS/NPPES records, not a clinical recommendation.
