Domain intelligenceDomain intelligenceReturns JSON with a domain's registration (RDAP: registrar, dates, status, DNSSEC), DNS records, SPF and DMARC, and recent TLS certificates.

Do not use when you need historical whois, registrant personal data (redacted by registries) or a port and vulnerability scan.
Price: 0.02 USDC per call (x402, eip155:8453). Typical response time: 4000 ms (p95).
