Deterministic, offline business-identifier verification and rental due-diligence for AI agents. 63 tools: IBAN/LEI/VAT/SWIFT/ABA/ISIN/GSTIN/ABN checks, UK company numbers, batch validation, rental deposit + listing risk, on-chain intelligence, and ISO 20022 → x402 intent. Paid per call via x402 (gasless EIP-3009 USDC on Base) — non-custodial, no signup, no API key. First 3 calls per day free per client, then from $0.005/call. Every response carries an offline-verifiable signed receipt, and a scope field stating exactly what was and was not checked (checksum-verifiable vs format-only — no overclaiming).
