Tool
Free public tool. Query any domain against the authoritative registry RDAP server — see who owns it, when it expires, whether it’s in redemption or pending delete, and what lifecycle state the registry reports. No login or signup required; we cache registry responses briefly and rate-limit abusive bursts.
How it works
Each query hits the authoritative registry RDAP server via rdap.org. Results are cached for 6h so back-to-back lookups don’t hammer the registry — and so you don’t wait on a slow network round trip twice.
