Changelog

1.0 (2026-10-07)

First version.
Availability and registration data for up to 5,000 domains per run from the registries' RDAP services, found through the IANA RDAP bootstrap file: registrar and IANA id, created / changed / expiry dates, days to expiry, status codes, name servers, DNSSEC, and the registrant's organisation and country only when the registry publishes them.
DNS-over-HTTPS check (A, AAAA, MX) to tell registered but unused domains.
Name ideas combined with a TLD list to generate candidates.
Watch mode: only domains that expire within N days or whose availability, registrar, status, name servers or expiry date changed since the last run.
TLDs without RDAP return a free info row; port-43 WHOIS is never used.
Pay per event: domain-checked at $0.0005. Unknown-TLD rows and error rows are free.
