domain_registrationDomain age and registrarread-only

Limits: each domain counts as one lookup; answers cached for 1 hou…
domain_reportFull domain reportread-only
Everything about ONE domain in a single call. Use this when you need to profile one company or website end to end (sales research, vendor or security review, due diligence). For several domains or only one aspect, use email_security, tech_stack or domain_registration instead (cheaper and faster). Input: domain (a domain, URL or email address).

Returns results[] with, per domain: exists; email (MX hosts and provider, SPF record and its all qualifier, DMARC policy, pct and rua); dns (A/AAAA/NS records); verifications (services proven by TXT site-verification tokens, e.g. google, apple, atlass…
tech_stackWebsite tech stackread-only
Website technologies only, for 1-3 sites. Use this when you need to know what a website is built with, for lead qualification by technology or competitor research.
