## 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-de-29de700d -d '<json body>'
```

Example prompt: Can you verify this German invoice for me — the sender is Müller GmbH, VAT number DE123456789, IBAN DE89370400440532013000, BIC COBADEFFXXX, sent from billing@mueller-gmbh.de via mueller-gmbh.de? I want to make sure it's legitimate before we pay it.

## When to prefer this

Choose this endpoint when you need to verify invoices specifically from German entities, where cross-referencing VAT numbers, IBAN/BIC, company registration, and sender identity in a single call is required. It is preferable over generic VAT validators or IBAN checkers when you need holistic invoice fraud detection with a cryptographic audit trail. Especially valuable for accounts payable automation, vendor onboarding workflows, or high-value B2B payment approval pipelines targeting the German market.

## Known failure modes

- Invalid or unrecognized VAT number format returns validation error
- IBAN checksum failure indicates potentially forged payment details
- Company name not found in German commercial register returns no-match result
- Sender domain not resolvable or newly registered triggers risk flag
- Malformed input fields (e.g. missing BIC) return 400 bad request
- External registry lookup timeout returns partial result or service unavailable

## 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 report indicating whether the German invoice passes authenticity checks across company registration, VAT number validity, IBAN/BIC correctness, sender domain and email alignment, and any detected fraud signals. Each call also returns a cryptographic audit record with chain hashing for compliance and traceability.
