Can I check if a domain is available for registration?

Yes! Use `check_domain_availability` with the domain name. It analyzes the WHOIS record to determine if the domain appears unregistered.

How many domains can I look up at once?

Use `bulk_whois_lookup` with a comma-separated list of up to 10 domains to get key registration details for each one in a single request.

Can I find which domains are hosted on a specific server?

Yes! Use `lookup_hosted_domains` with an IPv4 or IPv6 address to perform a reverse IP lookup and discover all domains on that server.
