What is WHOIS?

WHOIS is a public database that stores domain registration details. It's useful for:

  • Checking if a domain is available before buying
  • Finding the registrar or hosting provider
  • Seeing when a domain expires (useful for monitoring)
  • Identifying the nameservers (DNS hosting)

API Integration

This tool is also available as a free API. Send a POST request to /api/whois with a JSON body containing the domain field. The response includes parsed fields (registrar, dates, nameservers, status, DNSSEC) plus the raw WHOIS text. Rate limited to 30 requests per minute.

Privacy: Only the domain name you enter is sent to the server. No data is stored.
