## 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 veriffr-vat-number-validation-api-04fdfcf2
```

Example prompt: Can you check whether the French VAT number FR40303265045 is valid and tell me the company name and address it's registered to?

## When to prefer this

Choose this endpoint when you need to validate a French or EU VAT number and retrieve the associated company name and address in a single call, without needing an account or API key. It is ideal for ad-hoc compliance checks, supplier onboarding, or invoice validation workflows where pay-per-call USDC pricing is acceptable. Prefer alternatives if you need bulk VAT validation or non-EU tax ID verification.

## Known failure modes

- Invalid or malformed VAT number returns valid: false with no company details
- VAT number without two-letter country prefix may cause a bad request error
- Non-EU or unsupported country prefix may return an error or invalid result
- Payment failure via x402/USDC may block the request entirely
- Rate limits or service downtime on the Vercel-hosted backend may cause 5xx errors

## How this service works

Verify French companies, EU VAT numbers, and addresses from one API. Pay per call with USDC on Base via x402. No account, no API key.

## Output

A JSON object containing the submitted VAT number, a boolean validity flag, the registered company name, the full registered address, and the two-letter country code (e.g. FR).
