Yes! Use the check_domain_availability tool. It provides a lightweight check to see if a specific domain name is currently available.

How do I find the physical location of an IP address?

Simply use the get_ip_geolocation tool with the target IP. The agent will return the country, city, latitude, longitude, and ISP information.

Can this tool detect disposable or fake email addresses?
