Tools

• dns_records ~76 tokens
  DNS records for a domain: A, AAAA, MX, TXT, NS, CAA and SOA, resolved in parallel.
• domain_lookup ~226 tokens
  Full report on a domain in one call: WHOIS/RDAP registration, DNS records, live SSL certificate, subdomains (live hosts with IPs first) and email authentication (SPF, DMARC, DKIM). Use it to triage a suspicious domain or profile a company's domain. If one section fails it comes back as a
• email_security ~116 tokens
  Email authentication for a domain: SPF and DMARC records, and DKIM keys found by probing about 29 common selectors (Google, Microsoft 365, Mailchimp, SendGrid and others). Custom selectors may not be found.
• ssl_certificate ~106 tokens
  The certificate a domain serves on port 443, from a live TLS handshake: issuer, subject, valid_from, valid_to, days_until_expiry, SANs, signature algorithm and serial number.
• subdomains ~199 tokens
  Subdomains of a domain from certificate transparency logs, passive DNS and DNS brute force. `live` lists hosts that resolve now, each with its IP; `subdomains` lists every name found, live first; `pools` summarises large shared-infrastructure zones. The first lookup of a domain is a fast
• whois_lookup ~136 tokens
  Registration data for a domain: registrar, created, updated and expiry dates, nameservers and status. RDAP first (rdap.org, IANA bootstrap, 22 fallback servers), then port-43 WHOIS for 60+ TLDs. `_source` says which one answered. Use it for domain age, expiry or registrar checks.
