Api Endpoint

Otto AI x402 — Market Intelligence, DeFi & Tools

Domain age and registration intel from authoritative RDAP/WHOIS records: exact creation date, age in days and years, expiration date and days-until-expiry. The fast trust and risk signal agents use to vet a counterparty, link, or sender and to flag newly-registered or soon-to-expire domains. Returns structured JSON, keyless, pay-per-call. ccTLDs without RDAP return an uncharged 503.
