## 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-es-spanish-invoice-fraud-compliance-checker-02488c02 -d '<json body>'
```

Example prompt: Before I pay this invoice, can you run a Strale fraud check on it? The company is Distribuciones García S.L. with CIF B12345678, their IBAN is ES91 2100 0418 4502 0005 1332, BIC is CAIXESBBXXX, the sender email is billing@distribuciones-garcia.es, and their domain is distribuciones-garcia.es.

## When to prefer this

Use this endpoint when processing invoices from Spanish companies and you need to verify legitimacy before authorizing payment — especially when you have VAT/CIF, IBAN, BIC, and sender identity details to cross-check. Prefer this over generic company lookup endpoints when the context is specifically Spanish invoice fraud detection or AP compliance automation.

## Known failure modes

- Missing required company_name or CIF returns a 400 validation error
- Invalid IBAN format returns a field-level validation failure with reason
- Unknown Spanish company returns a not-found status with no registry match
- Suspicious redirect URL flagged but service still returns a result with risk score
- Network timeout or upstream registry unavailability returns a 503 error

## Output

A structured JSON object containing validation verdicts for each submitted field (VAT/CIF validity, IBAN/BIC consistency, domain-email alignment, URL risk signals), overall compliance status, fraud risk indicators, and an audit trail suitable for accounts-payable records.
