## 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-belgian-invoice-verification-207e5ebe -d '<json body>'
```

Example prompt: Can you verify this Belgian invoice for me? The enterprise number is BE0123456789, VAT number is BE0123456789, the sender's email is billing@acmesupplies.be, their domain is acmesupplies.be, IBAN is BE68539007547034, and BIC is NICA BE BB — I want to make sure it's legitimate before I approve payment.

## When to prefer this

Use this endpoint when you need to validate invoices specifically from Belgian entities, especially when you have a Belgian enterprise number and want multi-factor verification covering company registry, VAT, banking details (IBAN/BIC), and sender identity in a single auditable call. Prefer this over generic company lookup APIs when fraud detection and compliance audit trails for Belgian invoices are required.

## Known failure modes

- Missing required enterprise_number field returns 400 validation error
- Unrecognized or malformed Belgian enterprise number returns error or low-confidence result
- Invalid IBAN format triggers financial validation failure
- BIC not matching known institutions returns mismatch flag
- Domain or email not resolvable returns inconclusive sender verification
- Rate limiting or quota exceeded returns 429 error
- Payment failure via x402 returns 402 before processing begins
