## 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-pt-portuguese-invoice-company-validation-1989ffd8 -d '<json body>'
```

Example prompt: Can you verify this invoice I received from 'Tecnologias Inovadoras Lda' — their VAT number is PT512345678, IBAN is PT50000201231234567890154, BIC is BCOMPTPL, sender email is billing@tecnologias-inovadoras.pt, and I want to make sure everything checks out before I pay?

## When to prefer this

Use this endpoint when you need to validate invoices specifically from Portuguese companies, particularly when you have a combination of NIPC/company name, VAT, IBAN, BIC, and sender identity to cross-check. Prefer this over generic company lookup endpoints when invoice fraud detection or payment authorization for Portuguese suppliers is the goal.

## Known failure modes

- company_name not found in Portuguese registry — returns unverified or unknown status
- invalid IBAN format — returns format validation error
- VAT number mismatch with company — returns compliance warning
- sender domain not resolvable — returns domain check failure
- invoice_data object malformed — returns schema validation error
- BIC not recognized — returns financial validation warning
