## 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`):

Example prompt: Can you validate the EU VAT number DE345789012 — I need to know if it's properly registered before I issue this invoice, and I'll need an audit receipt for our records.

## When to prefer this

Choose this endpoint when you need authoritative EU VAT validation backed by the official VIES system, with both a fast local pre-check and a durable audit receipt. Prefer it over generic VIES wrappers when compliance documentation is required, or when you need retry logic and caching for reliability. Ideal for invoice processing pipelines, B2B onboarding flows, and tax compliance audits across EU member states.

## Known failure modes

- Invalid VAT number format — fails local prefilter before VIES is even queried
- VIES service temporarily unavailable for a specific member state — returns unavailable status with retry information
- VAT number not found in VIES — returns invalid with authoritative confirmation
- Network timeout on VIES — endpoint retries automatically but may still time out
- Unsupported country prefix — non-EU VAT numbers are rejected at format stage

## How this service works

Validate an EU VAT number: local format + check-digit prefilter, authoritative VIES check with retry and cache, durable audit receipt.

## Output

Returns a structured response including: local format validity, check-digit pass/fail, authoritative VIES registration status (valid/invalid/unavailable), the business name and address if returned by VIES, and a durable timestamped audit receipt suitable for compliance documentation.
