## 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 getapi-vat-number-validation-45bf2859 -d '<json body>'

## When to prefer this

Use this endpoint when you need real-time EU VAT number validation with enriched company data (name and address) in a single call. It is ideal for B2B invoicing workflows, supplier onboarding, checkout tax exemption flows, and compliance audits where you need to confirm a counterparty's VAT registration status. Prefer this over manual VIES lookups when you need programmatic access at $0.01 per call with no API key management overhead.

## Known failure modes

- Invalid or malformed VAT number format — returns valid: false with an error message
- VAT number not found in VIES registry — returns valid: false
- Unsupported country prefix — may return an error or invalid response
- VIES service temporarily unavailable — may return an upstream error
- Empty or missing vat_number field — likely returns a validation error
