## 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-belgium-0f938e68 -d '<json body>'
```

Example prompt: I just received an invoice from supplier TechBelgium BVBA — can you verify it? Their enterprise number is 0456.123.456, VAT BE0456123456, IBAN BE68 5390 0754 7034, BIC NICA BE BB, sender email is billing@techbelgium.be, domain techbelgium.be, and there's a payment redirect to https://pay.techbelgium.be.

## When to prefer this

Choose this endpoint when you need to verify Belgian invoices specifically, combining multiple data signals (enterprise registry, VAT, banking details, domain/email, and URL reputation) in a single audited call. Prefer it over generic VAT or IBAN validators when the invoice is Belgian and you need a holistic fraud-detection result with a cryptographic audit trail for compliance purposes.

## Known failure modes

- Invalid or malformed IBAN returns field-level validation error
- Unrecognized Belgian enterprise number returns not-found status
- VAT number format mismatch triggers format validation failure
- Unreachable or suspicious redirect URL flagged with connectivity/reputation warning
- Missing required fields returns 400-level error with field specification
- API payment failure via x402 protocol prevents call execution

## 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 the validity status of each submitted field (enterprise number, VAT, IBAN/BIC, sender domain, email, redirect URL), along with fraud risk signals, field-level mismatch details, and a cryptographically hashed audit record for traceability.
