How this service works
Pay-per-call APIs for AI agents: EU VAT validation (VIES) and website SEO/compliance check. USDC on Base via x402.
Output
A JSON object containing: 'valid' (boolean indicating VIES registration status), 'name' (registered business name or null), 'address' (registered address or null), 'checksumOk' (boolean or null for local checksum validity), and 'source' (string indicating the data source used).
Example use cases
Pre-invoice supplier VAT check
“Before I pay this invoice from a German supplier, can you verify that their VAT number DE298736890 is actually registered and tell me what company name it's linked to?”
Onboarding EU business customer
“We're onboarding a new B2B client from France — can you validate their VAT number FR83404833048 and confirm the registered business name and address match what they gave us?”
Automated compliance audit
“I have a list of EU vendor VAT numbers I need to verify for our compliance audit — start with IT00743110157 in Italy and tell me if it's valid, the checksum result, and the registered company details.”

Endpoint
GEThttps://z2r-agent-api.netlify.app/api/vat?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, programmatic EU VAT validation directly against the official VIES database, especially in agentic or automated workflows where per-call micropayment via USDC on Base is acceptable. Prefer it over manual VIES web lookups or batch validation services when you need a structured JSON response suitable for downstream processing without building your own VIES integration.
Side effects
- Invalid or malformed VAT number format returns valid: false
- VIES service temporarily unavailable may return an error or degraded response
- Unsupported or non-EU country code returns an error
- Payment failure via x402 prevents the call from completing
- VAT number exists but VIES returns no name/address (null fields) for some member states
