## 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 drug-price-lookup-nadac-per-unit-12ce369d
```

Example prompt: What's the current NADAC price per unit for atorvastatin 10 mg tablet — pull up to 5 results from the CMS Medicaid drug pricing data.

## When to prefer this

Use this endpoint when you need official, government-sourced drug acquisition cost benchmarks (NADAC) from CMS/Medicaid. Ideal for pharmacy cost comparisons, formulary analysis, drug pricing transparency tools, or any use case requiring authoritative per-unit pricing. Prefer this over commercial drug pricing APIs when you need free, public-domain data with no signup or API key, payable per call in USDC.

## Known failure modes

- No results returned if NDC or name does not match any records in the dataset
- Invalid NDC format (non-11-digit) may return empty results or an error
- Limit out of range (less than 1 or greater than 100) may cause a validation error
- Drug pricing data may lag behind real-world changes since it reflects NADAC survey periods
- Missing both 'ndc' and 'name' query params may return all records up to the default limit

## How this service works

Look up US drug pricing from CMS NADAC (National Average Drug Acquisition Cost) — the benchmark per-unit acquisition cost CMS surveys from retail pharmacies and publishes weekly. Pass ndc (11-digit National Drug Code) for an exact product, or name (drug name/description keyword, e.g. 'atorvastatin 10 mg') to search. Returns rows with the NDC, description, nadacPerUnit (USD per pricing unit), pricingUnit (EA/ML/GM), effectiveDate, OTC flag, and brand/generic classification — most recent effective date first. Real surveyed acquisition costs instead of model-guessed prices. Public domain; the current-year dataset is resolved automatically. NADAC is an acquisition-cost benchmark, not a retail or insured price.

## Output

A JSON array of matching drug records, each including the 11-digit NDC code, drug description, NADAC price per unit, pricing unit (e.g. EA), effective date, as-of date, OTC flag, and classification (brand/generic). Also includes total result count, dataset year, and data source attribution from CMS/Medicaid.
