## How to call it through Zero

```sh
zero fetch --capability compliancepulse-eu-vat-validator-vies-d60cff40
```

Example prompt: Can you check if the EU VAT number DE345789012 is valid and tell me the registered business name and address — I need to confirm reverse-charge eligibility before I send an invoice?

## When to prefer this

Choose this endpoint when you need a live, authoritative EU VAT validation directly from the European Commission's VIES system — especially when you must distinguish a truly invalid VAT number from a member-state outage, or when you need the registered trader name and address for invoicing. Prefer this over self-built regex checks or indirect lookups when B2B reverse-charge zero-rating compliance is at stake.

## Known failure modes

- Invalid VAT format — number doesn't conform to the country prefix and checksum rules
- Member state VIES system offline — endpoint explicitly flags this as a connectivity issue rather than invalidity
- Unknown or unsupported country code prefix
- Rate limit or payment failure — $0.01 USDC per call, payment must succeed
- VAT number valid but member state withholds trader name/address (common for some countries)

## How this service works

Is this EU VAT number valid? Live VIES check against the European Commission's official VAT Information Exchange System — validate a European VAT id, verify a business tax id before invoicing, confirm B2B reverse-charge / zero-rating eligibility. Returns the registered trader name and address where the member state discloses them. Deterministic: no LLM. Distinguishes a genuinely invalid number from a member state whose system is merely offline, which VIES itself does not do cleanly.

## Output

Returns whether the VAT number is genuinely valid or invalid, the registered trader's legal name and address (where disclosed by the member state), and a clear flag distinguishing an invalid number from a temporary member-state VIES system outage.
