## 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-swiss-invoice-verification-203108c0 -d '<json body>'
```

Example prompt: I just received an invoice from Mustermann AG (Swiss UID CHE-123.456.789) with VAT number CHE-123.456.789-MWST, IBAN CH56 0483 5012 3456 7800 9, BIC CRESCHZZ80A, sent from billing@mustermann.ch — can you verify this invoice is legitimate before I approve payment?

## When to prefer this

Use this endpoint when you need to validate invoices specifically from Swiss companies, where Swiss-specific registries (UID, MWST/VAT, Swiss IBAN format) are involved. Prefer this over generic invoice validation when you need Swiss compliance data, audit trails for accounts payable workflows, or multi-factor cross-checking of company identity alongside financial details.

## Known failure modes

- Missing required company_name field returns 400 validation error
- Unrecognized Swiss company name or UID returns no-match result
- Invalid IBAN format causes financial validation failure
- BIC/SWIFT code not recognized returns unknown-institution result
- Rate limiting or payment failure returns 402 or 429
- Swiss registry unavailable causes partial result with degraded confidence

## How this service works

Company data, compliance checks, financial validation. Structured JSON with audit trails. Every capability independently quality-scored.

## Output

A structured JSON object containing the verification outcome for the Swiss invoice, including company identity validation against Swiss registries, VAT number status, IBAN/BIC correctness, sender domain and email trustworthiness assessment, and a full audit trail of checks performed.
