## 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 fda-establishment-screen-firm-name-search-136b9529
```

Example prompt: Can you search FDA establishment records for 'Pfizer Manufacturing' and return up to 10 ranked facility candidates — only drug manufacturers — so I can find the right FEI number?

## When to prefer this

Use this endpoint as a cheap first screening step before calling a detailed FDA facility lookup. Ideal when you have a firm name but not yet a FEI number. Best for compliance workflows, supply chain due diligence, pharmaceutical research, and regulatory intelligence tasks where you need to identify the correct FDA-registered establishment for a manufacturer.

## Known failure modes

- No matching firms found for the given name — empty candidates list returned
- Invalid or unsupported product type enum value causes validation error
- State code not recognized (non-US 2-letter code) — may return unfiltered or empty results
- Name query too generic returns too many candidates; narrowing with state/country/product recommended
- Rate limiting or payment failure if x402 payment not properly handled

## How this service works

Search FDA-regulated manufacturers in the public FDA establishment records by firm name and get ranked facility candidates, each with its FDA FEI number, location, product types, inspection count and latest inspection classification. Cheap first step before fda/facility.

## Output

A ranked list of up to 25 FDA-registered facility candidates matching the search name, each containing: FDA FEI number, facility name, address/location, registered product types (Drugs, Devices, Biologics, etc.), number of FDA inspections, and the classification of the most recent inspection.
