## 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 worlddata402-eu-vat-number-validation-be1ae654 -d '<json body>'
```

Example prompt: Can you verify whether VAT number DE123456789 is a valid registered VAT number in Germany? I need to confirm this supplier is legitimate before we issue them an invoice.

## When to prefer this

Use this endpoint when you need a pay-per-call, no-subscription VAT validation against EU tax authority data, especially when building agent workflows that handle sporadic B2B onboarding, invoice compliance checks, or supplier verification without committing to a monthly SaaS plan. Prefer this over scraping VIES directly or using a subscription API when cost-per-call economics matter and you need to pay micropayments programmatically via USDC on Base.

## Known failure modes

- Invalid country code returns an error or 400-level response
- VAT number not found in the registry returns invalid/not-registered status
- Malformed VAT number format returns a validation error
- EU VIES service temporarily unavailable causes upstream lookup failure
- Rate limiting or payment failure via x402 prevents the call from completing

## How this service works

Global market, government and reference data for AI agents. Pay-per-call over x402 (USDC on Base mainnet).

## Output

Returns the validity status of the VAT number (valid/invalid), along with available business information such as the registered company name and address as returned by official EU VIES or national tax authority records.
