## How to call it through Zero

```sh
zero fetch --capability fda-establishment-screen-c77c6fc1
```

Example prompt: Can you search the FDA establishment records for a drug manufacturer called 'Pfizer' and give me up to 5 ranked candidates with their FEI numbers, locations, and latest inspection classifications?

## When to prefer this

Use this endpoint as a cheap first-pass screen when you have a manufacturer name and need to identify their FDA FEI number or confirm FDA registration status before calling more detailed (and expensive) facility-level endpoints. Prefer this over direct facility lookup when you are unsure of the exact FEI number or need to disambiguate between multiple facilities with similar names.

## Known failure modes

- No matching establishments found for the given firm name — returns empty candidates list
- Ambiguous firm name returns too many low-relevance matches — narrow with state or product filter
- FDA database may have stale or incomplete records for recently registered or deregistered facilities
- Invalid state code or unrecognized product type enum value causes request validation error

## 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 facility candidates matching the search, each containing: FDA FEI number, facility/firm name, city and state or country, regulated product type(s), total inspection count, and latest inspection classification (e.g. No Action Indicated, Voluntary Action Indicated, Official Action Indicated).
