## 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-invoice-verify-us-fb17f086 -d '<json body>'
```

Example prompt: I just received an invoice from Acme Corp (EIN 12-3456789, sender email billing@acmecorp.com, domain acmecorp.com) with IBAN GB29NWBK60161331926819, BIC NWBKGB2L, and VAT number US123456789 — can you verify this invoice is legitimate before I approve payment?

## When to prefer this

Use this endpoint when you need to verify a US-context invoice before approving payment, especially when checking for business email compromise (BEC), invoice fraud, or vendor impersonation. It combines multiple identity signals (EIN, VAT, IBAN, BIC, email, domain) in a single call with a cryptographic audit trail — prefer it over single-signal validators when you need holistic invoice trust scoring and compliance documentation.

## Known failure modes

- Unrecognized EIN or company name returns low-confidence or unverified status
- Invalid IBAN checksum triggers format validation failure
- Unknown or newly registered sender domain may return insufficient data
- VAT number not matching US format returns format error
- Missing required fields (e.g. no company_name or invoice_data) may return partial results or error
- Redirect URL unreachable or flagged as suspicious returns warning signal

## 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 structured verification result indicating whether the invoice details are consistent and legitimate, including checks on company identity (EIN/VAT), banking details (IBAN/BIC validity), sender domain and email authenticity, and redirect URL safety. Each response includes a cryptographic audit record with chain hashing for traceability.
