}Comprehensive Domain Risk & Security Auditing
Domain Intelligence API is a cybersecurity & WHOIS audit API that queries domain registration age, expiration date, registrar details, SSL certificate status, and DNS records (A, MX, TXT, DMARC, NS) in structured JSON format.
Cybersecurity security operations centers (SOCs), brand protection software, and domain investors require instant visibility into domain registration history and infrastructure setups. Our Domain Intelligence API performs complete domain audits in a single HTTP request.
Every API audit returns: WHOIS domain creation date, age in years, expiration date, registrar entity, SSL certificate issuer, validity status, days remaining until SSL expiration, DNS record sets (A, AAAA, MX, TXT/SPF/DMARC, NS), and server HTTP status headers.
Identify newly registered domains (NRDs) often associated with phishing campaigns, monitor SSL certificate expiration timelines for IT compliance, and audit mail server DNS records (SPF, DKIM, DMARC) to prevent email spoofing.
