What it does
Paste a list of full domains, or try base names across a list of TLDs. The tool looks up each name on official registry RDAP servers listed by IANA, which covers about 590 TLDs.
Each row comes back as available, registered, likely_available, unsupported_tld, invalid or error. For taken names you get the registrar, IANA registrar id, creation and expiry dates, nameservers, status codes and DNSSEC. Registrant contacts are never collected.
likely_available means the TLD has no public RDAP server and DNS says the name does not exist. Confirm those at a registrar before you treat them as a firm yes.
Who it is for
It is for people who need a straight available-or-taken answer on a long list, without harvesting personal WHOIS contacts.
- Brand and domain researchers trying a name across popular TLDs.
- SEO and marketing teams checking expiry and registrar details on a list of properties.
- Developers and automations that need a predictable API for official registry data.
Price
$1 per 1,000 checked domains ($0.001 per domain). That is the live Apify Store price as of November 11, 2026.
You pay for available, likely_available and registered rows. Invalid input, unsupported TLDs and errors are free. 50 names times 20 TLDs is 1,000 domains, or $1.00.

}Questions
Where do the answers come from?
Official registry RDAP servers listed by IANA. RDAP is the modern replacement for WHOIS. The tool uses IANA's bootstrap file, which covers about 590 TLDs.
Do you collect registrant contacts or personal data?
No. For registered names you get registrar, dates, nameservers and status codes. Registrant contacts are not collected.
What does likely_available mean?
The TLD has no public RDAP server, and DNS says the name does not exist. Confirm it at a registrar before you treat it as a firm yes.
Can I try one brand name across many TLDs?
Yes. Give it base names and a list of TLDs, for example com, net, io, dev, and it checks each combination.
What is free?
Invalid input, unsupported TLDs and errors are not charged. You pay for available, likely_available and registered rows.
