Domain Availability Checker – Bulk RDAP (any TLD)

Check if domains are available using official RDAP registries, plus registrar, created and expiry dates for taken ones. Combine brand names with TLDs in one run.

Why this actor

• Name × TLD combinator and official RDAP data; no reseller API key needed.

  "created": "2009-06-02T17:14:10Z",
