ActiveTool of LION - keyless attested data for AI agents
Keyless EU VAT number validation for KYB / compliance - no API key, no signup, payment is the only gate. Pass an EU VAT number (?vat=IE6388047V, or ?country=IE&number=6388047V) and get ONE structured JSON: valid (bool), company_name, address, country_code, vat_number, request_date. A cryptographically-provable single-field VAT check - Ed25519-attested (verify offline), a narrow VERIFIABLE niche, NOT a broad compliance suite - sourced live from the EU Commission VIES service (ec.europa.eu), keyless, authoritative. EU member states + Northern Ireland (XI). Business-registration public record only; the buyer supplies the VAT number to validate. $0.005 USDC on Base via x402. Not legal or tax advice. [x402 paid tool: GET /api/x402/vat-validation-json?src=mcp returns the 402 challenge with the canonical payTo; price 0.005 USDC on Base eip155:8453.]
