Domain Intelligence

oti-labs/domain-intelligence

WHOIS/RDAP, DNS, SSL, live subdomains with IPs, and SPF/DMARC/DKIM for any domain. Six read-only tools: - `domain_lookup`: everything below in one call - `whois_lookup`: registrar, created and expiry dates, nameservers (RDAP first, then port-43 WHOIS) - `dns_records`: A, AAAA, MX, TXT, NS, CAA, SOA - `ssl_certificate`: live TLS handshake: issuer, expiry, days left, SANs - `subdomains`: live hosts with their IPs, split from historical names - `email_security`: SPF, DMARC, DKIM No key needed to start. For your own monthly allowance, add a free RapidAPI key (1,000 requests a month) as X-RapidAPI-Key in the connection settings. Open source (MIT).
