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.
Example use cases
Supplier due diligence before payment
“Before I pay this new supplier, can you check if their VAT number FR40303265045 is actually registered in France? I want to make sure they're a legitimate business.”
Invoice compliance check for EU B2B
“We're sending a B2B invoice to a company in the Netherlands and their VAT number is NL123456789B01 — can you verify it's valid so our invoice is compliant?”
Onboarding a new EU business customer
“A new customer from Italy just signed up and gave us VAT number IT12345678901 — can you validate it and pull back whatever business details are available so I can complete their account profile?”

Endpoint
POSThttps://worlddata402.worlddata402.workers.dev/v1/eu/vat/%7BcountryCode%7D/%7BvatNumber%7D?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
