Tools 6 found in our last check

  • domain_lookup

    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…

  • whois_lookup

    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.

  • dns_records

    DNS records for a domain: A, AAAA, MX, TXT, NS, CAA and SOA, resolved in parallel.

  • ssl_certificate

    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

    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…

  • email_security

    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.
