Pricing

• MCP endpoint: 20 free tool calls per day per IP, no signup. When the quota is used up, the tool returns an error that points to the paid options below.
• REST API with x402 on the same host (https://eu-vat-checker.onrender.com, e.g. GET /verify?vat=..., POST /verify/batch, GET /company?q=..., sanctions, KYB and EORI routes): after the free allowance, calls are paid per request with x402 in USDC on Base: about $0.01 per single check, $0.10 per batch, $0.03 per KYB check. Unpaid calls get HTTP 402 with the payment requirements.
