## 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 vat-validate-4cdc2f54 -d '<json body>'
```

Example prompt: Can you check whether the VAT number DE123456789 is valid and actively registered?

## When to prefer this

Use this endpoint when you need to verify that a customer or supplier's EU VAT number is correctly formatted and actively registered before issuing invoices, applying zero-rated VAT, or onboarding a business partner. Prefer this over manual checks or the Calculate endpoint when you only need validation status, not rate computation.

## Known failure modes

- Invalid VAT number format returns validation failure with format error
- VAT number not found in EU VIES database returns not valid
- Missing vat_number field returns 400 bad request
- Unsupported country prefix returns error or invalid result
- Temporary VIES database unavailability may return uncertain or error response
