Monitor when domains expire to prevent accidental lapses or plan acquisition of expiring domains.

A domain that lapses because someone forgot to renew it is one of the most preventable and costly infrastructure failures. When a domain expires, your website goes down, your email stops working, and in the worst case, someone else registers it. Even for domains you do not own, knowing expiration dates is valuable -- expired domains in your industry can be acquisition opportunities.

The lookup_domain skill retrieves the exact expiration date for any domain, along with the registrar and auto-renewal status where available. You can check your own domains to verify renewals are on track, monitor competitor or partner domains for changes, and watch domains you want to acquire. This simple check prevents expensive outages and reveals acquisition opportunities.
