## 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-fr-f8a6f209 -d '<json body>'
```

Example prompt: Can you verify this French invoice for me? The sender is factures@boulanger-sarl.fr from boulanger-sarl.fr, their SIREN is 552 032 534, VAT number FR83552032534, IBAN FR7630006000011234567890189, and BIC BNPAFRPP — I want to make sure it's legitimate before we pay.

## When to prefer this

Use this endpoint when you need to verify French invoices specifically, particularly when you have multiple data points (SIREN, VAT, IBAN, BIC, sender email/domain) and want cross-registry validation with a cryptographic audit trail. Prefer this over generic invoice validation endpoints when the invoicing entity is French and you need SIREN/SIRET registry checks. It is especially valuable in accounts-payable automation, supplier onboarding, and anti-fraud workflows where an immutable audit record per verification call is required.

## Known failure modes

- Invalid or malformed SIREN/SIRET returns a format validation error
- IBAN checksum failure returns invalid IBAN error
- Unknown or unresolvable sender domain returns a lookup failure
- French business registry unavailable returns a temporary service error
- Missing required fields returns a 400 bad request with field-level detail
- VAT number not found in EU VIES returns unverifiable VAT status

## 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 each provided field (SIREN/SIRET, VAT number, IBAN, BIC, sender email, sender domain, URL) passes or fails validation against French business registries and fraud signal databases. Includes an overall authenticity verdict, per-field status flags, detected anomalies or fraud signals, and a cryptographically hashed audit record for compliance traceability.
