## 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.
