Questions and answers

Why is the slug still whois-lookup?

The registry slug is preserved for compatibility, while the production implementation uses modern RDAP rather than WHOIS scraping.

Can this check domain availability?

No. Purchase availability requires the relevant registrar or registry response at order time.
