## 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 citiview-vat-iban-bic-validator-5bd25cc3
```

Example prompt: Before I pay this invoice, can you check if VAT number DE811907980 is valid in the VIES register and also validate the IBAN DE89370400440532013000 and BIC COBADEFFXXX?

## When to prefer this

Choose this endpoint when you need to verify EU supplier legitimacy before paying an invoice, onboarding a vendor, or processing a bank transfer. It combines VIES VAT lookup (company name + address) with IBAN and BIC validation in a single call, making it ideal for accounts-payable automation, supplier onboarding workflows, and invoice fraud prevention. Prefer this over generic business lookup APIs when EU VAT compliance and banking detail verification are the specific need.

## Known failure modes

- VAT number not found in VIES (may be temporarily unavailable or genuinely unregistered)
- VIES service temporarily unavailable (EU system has known downtime)
- Invalid VAT format for the given country prefix
- IBAN fails checksum — returns invalid result
- BIC format does not conform to SWIFT standard — returns format error
- Missing required query parameter returns error

## How this service works

EU VAT number check against the official VIES register (valid, company name and address), plus IBAN checksum and BIC/SWIFT format validation. Check a supplier before paying an invoice.

## Output

Returns whether the VAT number is valid according to the VIES register along with the registered company name and address; IBAN checksum pass/fail; and BIC/SWIFT format validity. Helps confirm a supplier is legitimate before processing a payment.
