## 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-payment-validate-iban-vat-financial-validation-3de8afd2 -d '<json body>'
```

Example prompt: Can you validate this IBAN — DE89370400440532013000 — and VAT number DE123456789 to make sure they're legitimate before we process this supplier payment?

## When to prefer this

Use this endpoint when you need to simultaneously validate both a company's bank account (IBAN) and VAT registration number in a single call with a structured audit trail — ideal for vendor onboarding, B2B payment compliance, or KYB workflows where both financial and tax credentials must be verified together.

## Known failure modes

- Invalid IBAN format returns validation error with details
- VAT number not found in registry returns unverified status
- Malformed input JSON returns 400 bad request
- Payment of 0.27 USDC not fulfilled returns 402 Payment Required
- Network timeout or upstream registry unavailable returns 503

## How this service works

Verify bank details and tax IDs before your agent processes a payment. IBAN validation, bank identification, and counterparty VAT check.

## Output

A structured JSON object containing validation results for both the IBAN (format correctness, bank reachability, country) and VAT number (registration status, business identity match), along with an audit trail for compliance documentation.
