## 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

```

Example prompt: Pull me a list of the top 50 endocrinologists in Texas who prescribed Ozempic in 2024 with at least 100 claims, using the HealthParse Part D prescriber search.

## When to prefer this

Use this endpoint when you need to identify, rank, or target Medicare Part D prescribers of a specific drug or drug class at the individual NPI level — ideal for pharma sales targeting, market research, provider outreach lists, and competitive landscape analysis using public CMS data. Prefer this over general provider search endpoints when the primary filter is a drug name or therapeutic class rather than service volume or payment amount.

## Known failure modes

- Drug name not found in CMS Part D data — returns empty results or error
- Drug class value not in supported enum (GLP-1, SGLT2, DPP-4, Statin) — validation error
- Invalid 2-letter state code — no results or error
- Year not loaded (only 2023 and 2024 available) — error or empty response
- Overly restrictive filters (high min_claims + narrow specialty + rare drug) — empty result set
- Payment failure via x402 protocol — 402 response, no data returned

## How this service works

Find Medicare Part D prescribers of a specific DRUG or therapeutic CLASS at NPI level — the core pharma targeting query. Filter by drug_class (GLP-1, SGLT2, DPP-4, Statin, from partd_drug_class) or a single drug (brand or generic, e.g. 'Ozempic'), plus specialty, state, min_claims, min_beneficiaries, year. Each hit carries the drug's claim/cost volume and the prescriber's specialty/state/city. Public CMS provider-level data; not a consumer report.

## Output

A paginated list of Medicare Part D prescribers matching the query, each record containing the prescriber's NPI, name, specialty, state, and city, along with drug-specific metrics including total Part D claims, total drug cost, and total beneficiaries for the specified drug or drug class and year.
