Bulk Domain Checker – Availability, Age, Expiry
Pricing
from $0.30 / 1,000 domain checkeds
Check thousands of domains at once using official registry RDAP data and DNS: available or taken, creation date & age, expiry date, registrar, status, nameservers, DNSSEC, MX/mail provider, SPF and DMARC. No registrant personal data.
Domains or URLs to check (e.g. example.com, https://www.example.org/page, münchen.de). One per line.
Optional. Each keyword is combined with every TLD below (e.g. 'acmerobots' + com, io, ai) – great for brainstorming available names.
[]Add A/AAAA, MX + detected mail provider, SPF and DMARC records.
For registered domains, fetch the homepage: HTTP status, final URL, page title, HTTPS, parked-domain hint. Slower.
Output only domains confirmed available by a definitive registry RDAP 404. Domains whose status could not be confirmed ("unknown") are left out, and their count is in the RUN_SUMMARY (unknownExcludedFromOutput, unknownByReason). Every domain looked up is billed the small per-lookup fee; the per-result fee applies only to saved available domains. Website check is skipped in this mode.
