## When to prefer this

Choose this endpoint when you need a quick, pay-per-call EU VAT number validation without managing your own VIES API integration or API keys.

The free tier and no-API-key requirement make it suitable for prototyping or low-frequency lookups.

## Known failure modes

- Invalid VAT number format returns ok: false or an error message
- Country prefix not recognized or unsupported may return an error
- VAT number not found in EU VIES database returns invalid/not registered
- Network or upstream VIES service unavailability causes timeout or 5xx error
