## 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-verification-austrian-company-financial-validation-765bf002 -d '<json body>'
```

Example prompt: I just received an invoice from 'Mustermann GmbH' — can you verify it's a real Austrian company and that the payment details check out? The VAT number is ATU12345678, IBAN is AT61 1904 3002 3457 3201, BIC is RLNWATWW, and the sender email is billing@mustermann.at.

## When to prefer this

Use this endpoint when you need to validate an invoice received from an Austrian company and want a single call that cross-checks company registration, VAT, IBAN, BIC, and sender identity together with an audit trail. Prefer this over generic company lookup APIs when you specifically need invoice-level fraud detection and financial field validation in one structured response.

## Known failure modes

- Company name not found in Austrian register — returns validation failure with not-found status
- Invalid IBAN format — returns format error for the IBAN field
- VAT number not recognized — returns VAT lookup failure
- Missing required company_name field — returns 400 bad request
- Sender domain or URL unreachable for redirect tracing — returns partial result with domain check skipped
- Rate limiting or payment failure — returns 402 or 429 error
