## 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 strale-kyb-complete-us-8555d5ab -d '<json body>'
```

Example prompt: Run a full KYB check on Acme Corp — their EIN is 12-3456789, website is acmecorp.com, and the contact person is Jane Smith at jane@acmecorp.com.

## When to prefer this

Use this endpoint when you need a comprehensive, structured KYB report on a US company including compliance checks, PEP screening, and audit trails — especially in onboarding, due diligence, or vendor risk workflows where a single authoritative report with audit provenance is required.

## Known failure modes

- Company name not found in US registry — returns 404 or empty match
- Invalid EIN format — returns validation error
- Domain does not resolve or match registered company — low confidence score
- PEP screening unavailable for contact — partial result returned
- Downstream registry timeout — service returns 503
