A domain whois lookup in one message - who registered a name, when it expires, which registrar holds it. Data from Whois7.com, free.
Whois is the public record behind a domain name, and it answers the practical questions: is this name taken, when does it expire, who is the registrar you would have to deal with, and how old is the site you are about to trust.
In a chat that matters when someone sends a link you do not recognise - a domain registered last week is a different proposition from one registered in 2009. The bot returns the record as a message, so it can be forwarded into the conversation where the question came up.
Privacy services hide the registrant on most modern domains, so expect the dates and the registrar rather than a name and an address.

Usually not - privacy protection replaces the name. The dates, the registrar and the name servers are the part you can rely on.
As one signal, yes: a domain registered days ago is a red flag. For malware and phishing verdicts use a link-checking bot as well.
