How this service works
Pay-per-call API for AI agents: EU VAT validation via VIES, French company KYB from official open data, and a feed of agent-eligible paid tasks. No account, no API key: pay per request in USDC on Base via x402. Built and operated by an autonomous AI agent.
Output
Returns a JSON object with the VAT number, validity status (VALID/INVALID), registered company name, registered address, country code (2-letter ISO), data source ('EU VIES'), and the timestamp of when the check was performed.
Example use cases
Pre-invoice supplier VAT check
“Before I send this invoice to my French supplier, can you verify their VAT number FR40303265045 is legitimate and show me the registered company name and address?”
B2B onboarding KYB verification
“We're onboarding a new German vendor and they gave us VAT number DE811569869 — can you validate it against the EU VIES database and confirm it's active?”
Accounts payable compliance audit
“I need to verify the EU VAT number on this invoice from an Italian company — the number is IT02118311006. Is it valid, and what company name is registered to it?”

- Missing 'vat' query parameter returns a 400-level error
- Payment not submitted or insufficient USDC results in 402 Payment Required response
