$0.003 per call. Profile of one domain in one call: A, AAAA, MX, NS and CAA records, parsed SPF and DMARC, DKIM selector hints, mail provider, DNS provider, hosting or CDN, services verified in TXT records, homepage status and title, tech stack from homepage headers and HTML, TLS certificate issuer and expiry, and posture flags. Domains that do not exist, or DNS failures, return an error and are not charged. Invalid, IP or private names return 400, not charged. robots.txt is respected for the homepage. Sample at no charge: ?sample=1. DNS lookups via Cloudflare 1.1.1.1. Homepage and TLS certificate read directly from the domain. ?domain=example.com Use when: you want one cheap call that profiles a company or vendor domain: mail provider and SPF/DMARC posture, DNS and hosting providers, tech stack and TLS expiry, for lead enrichment, vendor checks or deliverability triage. Don't use when: you need raw DNS records of arbitrary types, WHOIS or registrar data, subdomain enumeration, full certificate chains, many pages of a site, or a security audit. Price: $0.003 per call over x402 (USDC on Base). Set sample:true for a sample at no charge.
