## Changelog

### 1.0 (2026-11-03)

- First version. Bulk RDAP lookups via the IANA bootstrap registry plus verified extra servers for .io, .co, .me, .sh, .ac; DNS-over-HTTPS fallback for extensions without RDAP.
- Name ideas x extensions mode, URL/subdomain/IDN normalization, dedupe, per-registry politeness with Retry-After.
- Pay per event pricing; invalid and failed domains are not charged.
- 2026-11-03: a run with empty input (API call or automatic test) checks the 5 example domains instead of failing.
- 2026-11-03: listing for AI agents: README "AI agents: quick call" block (minimal input, compact row, price, fields= tip), agent hints on Domains and Include raw RDAP JSON, description now leads with "Domain availability checker API for apps and AI agents". No change to price, limits or memory.
- 2026-11-04: Standby (fast API) mode: GET or POST /check on the Standby URL returns the rows as JSON in the HTTP response (up to 100 domains per request). Normal runs are unchanged. New event standby-request at $0.0005 per request that returns results; per-domain price unchanged.
