## 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 websterberry-synaptic-federal-contractor-lookup-747a3ba3
```

Example prompt: Can you check if Acme Defense Solutions is currently registered and active in SAM.gov — I need their CAGE code, registration expiration, and whether they have any exclusions?

## When to prefer this

Use this endpoint when you need to verify a US federal contractor's SAM.gov eligibility, registration status, or CAGE code prior to awarding or processing a government contract. Prefer this over general business lookup APIs when the specific context is federal procurement compliance, exclusion screening, or NAICS code verification tied to SAM.gov data.

## Known failure modes

- No matching entity found for the given UEI or business name — returns empty or not-found response
- Ambiguous business name matching multiple contractors — may return first match or require more specific input
- SAM.gov data may be slightly delayed if contractor recently updated registration
- Invalid UEI format (must be 12 characters) returns an error
- Network or upstream SAM.gov API unavailability returns a service error

## How this service works

Look up a US federal contractor in SAM.gov by UEI or legal business name: registration status and expiration, CAGE code, exclusion flag, NAICS codes and business types.

## Output

Returns the contractor's SAM.gov registration status (active/inactive), registration expiration date, CAGE code, whether the entity is excluded from federal awards, the NAICS codes they are registered under, and their business type classifications (e.g. small business, woman-owned, veteran-owned).
