Understand Any Domain in Seconds

Each domain page on WhoisJSON combines three data sources in one view: WHOIS registration data (registrar, creation/expiry dates, status), DNS records (A, MX, NS, TXT, SOA), and SSL certificate details (issuer, validity, encryption). Need this data programmatically? All three endpoints are available through a single API key — 1,000 free requests/month.

Stay Informed with Domain Monitoring

Don't just check once — monitor domains continuously. Get email alerts when WHOIS ownership changes, DNS records update, SSL certificates expire, or a domain becomes available for registration. Monitoring is included in every WhoisJSON plan.

Ready to integrate? Read the API documentation or check our FAQ to get started.
