Security — entry 007 of 30
Domain Intelligence
Domain Intelligence bundles DNS lookups, WHOIS/RDAP records, SSL certificate details, subdomain enumeration, and email-security posture (SPF/DKIM/DMARC auto-probed across common selectors) into a single parallel API call per domain. It's built and billed through RapidAPI, with a free Basic tier and metered overage pricing for higher-volume lookups. The combined response targets attack-surface reconnaissance and email-spoofing risk checks without stitching together several separate lookups yourself.
