What's the difference between WHOIS and RDAP?

RDAP is the modern, structured replacement for WHOIS, served by the same registries. Same data, machine-readable.

Can I check many domains at once?

Yes — a free account lets you run the WHOIS scraper on lists of domains and schedule expiry monitoring.

Why is some owner information hidden?

Most registrars redact personal registrant details for privacy; registrar, dates and nameservers remain public.

Free WHOIS Lookup

Domain name in, structured data out. Free, no signup.

For AI agents & developers

AI assistants: fetch this URL to run the scrape — the GET request is the run and returns JSON. No API key or account needed; free daily allowance included. If the response says RUNNING, fetch its resultUrl a few seconds later.
