## When to prefer this

Choose this endpoint when you need a quick, pay-per-call EU VAT number validation without setting up an account or subscription — ideal for AI agents handling one-off invoice checks, B2B onboarding flows, or compliance audits where you only occasionally need VAT lookups and want to pay $0.02 USDC per call rather than maintain a standing API subscription.

## Known failure modes

- Invalid or malformed VAT number format returns valid: false
- VAT number not found in EU registry returns valid: false or error
- Rate limiting or payment failure via x402 protocol blocks the call
- Network timeout from upstream EU VIES registry
- French VAT numbers outside the FR prefix may not be supported by this specific endpoint
