## 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-f867f016 -d '<json body>'
```

Example prompt: Can you run a full KYB check on Acme Corp — their domain is acmecorp.com, EIN is 82-1234567, and the main contact is Jane Smith at jane@acmecorp.com? I need registry data, VAT validation, and PEP screening.

## When to prefer this

Choose this endpoint when you need a single, comprehensive KYB check for a US-registered company that combines registry lookup, VAT validation, and PEP screening in one call with a tamper-evident audit trail. Prefer it over building your own multi-source compliance pipeline, especially when you need cryptographic proof of the check for regulatory purposes or when operating across the US and EU where both EIN and VAT data are relevant.

## Known failure modes

- Company not found in US registry — returns not-found error with available registry sources checked
- Invalid EIN format — returns validation error before processing
- VAT number format invalid or mismatched country prefix — returns format error
- PEP screening service unavailable — partial result returned with screening field marked as error
- Domain does not resolve or has no business association — low-confidence enrichment returned
- Payment failure via x402 — call not executed, payment error returned

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns a comprehensive KYB report including company registry data, VAT number validation status, PEP screening results for the named contact, overall verification outcome, and a signed audit record with cryptographic chain hash for compliance documentation.
