## How to call it through Zero

```sh
zero fetch --capability eu-vat-vies-live-validator-9b4352fe
```

Example prompt: Can you check whether the VAT number IE6388047V is actually registered in the EU VIES system, and tell me the business name it's registered under?

## When to prefer this

Use this endpoint when you need a live, real-time check against the official EU VIES registry — not just format validation. It is the right choice when you need to confirm a business is actively VAT-registered and retrieve their official registered name and address for invoicing, compliance, or onboarding purposes. Prefer it over offline format-only validators when the authoritative answer matters and you can tolerate occasional UNVERIFIED results due to member state outages.

## Known failure modes

- Member state VIES system unavailable — returns degraded:true with UNVERIFIED verdict rather than valid/invalid
- Invalid VAT number format — may return valid:false with reasons explaining the format issue
- VAT number not found in VIES — returns valid:false
- Missing country prefix or incorrect prefix (e.g. EL for Greece, not GR) — query may fail or return unexpected results
- Network timeout to VIES backend — may return null fields with error reasons

## How this service works

Live EU VIES check: is this VAT number registered, and under what name. Member state outages give UNVERIFIED.

## Output

Returns a JSON object with: `valid` (boolean or null), `verdict` (string summary), `name` (registered business name), `address` (registered address), `country` (ISO country code), `number` (normalized VAT number), `localFormat` (country-specific format), `asOf` / `requestDate` (timestamp of the VIES response), `degraded` (true if a member state system was unavailable), `reasons` (array of explanation strings), `summary` (human-readable summary), `source` and `sourceUrl` (VIES attribution), and `disclaimer`. If the member state system is down, `degraded` is true and the verdict may be UNVERIFIED.
