Verifies the availability of domain names across over 500 TLDs using RDAP and WHOIS protocols.

This tool provides a robust server for determining if a domain name is available for registration. It leverages the RDAP protocol for over 500 top-level domains, including popular gTLDs and ccTLDs, and offers WHOIS fallback for specific regions like .de and .cn. By extracting the TLD, routing to the appropriate adapter, and performing either an HTTP lookup (RDAP) or TCP port 43 query with pattern matching (WHOIS), it delivers a structured result indicating the domain's availability status. This makes it an essential utility for anyone needing programmatic domain availability checks.
