## 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-ch-c8423b21 -d '<json body>'
```

Example prompt: I just received an invoice from Muster AG claiming VAT number CHE-123.456.789, IBAN CH56 0483 5012 3456 7800 9, BIC CRESCHZZ80A, and sent from billing@muster-ag.ch — can you verify this Swiss invoice is legitimate before I approve the payment?

## When to prefer this

Use this endpoint when you need to verify the authenticity of a Swiss invoice before approving payment — specifically when you have structured invoice data including IBAN, BIC, VAT number, and sender domain/email. Prefer this over generic invoice validation endpoints when the invoice is from a Swiss entity and you need country-specific registry checks (Swiss UID, CHF IBAN format). The cryptographic audit record makes it suitable for compliance workflows requiring tamper-evident verification logs.

## Known failure modes

- Invalid or unrecognized Swiss VAT number format returns validation error
- IBAN checksum mismatch triggers format failure
- BIC not found in SWIFT registry returns unknown entity
- Company name or UID not found in Swiss commercial registry
- Sender domain has no verifiable link to the named company
- Missing required fields result in partial verification with reduced confidence
- Network timeout or upstream Swiss registry unavailability returns service error

## 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 whether the invoice sender's identity, IBAN, BIC, VAT number, and domain are consistent and legitimate for a Swiss company, along with fraud signals and an audit record with a cryptographic chain hash for traceability.
