DomainToolBelt

DomainToolBelt gives Claude the data a domain investor works with every day. Ask what similar names sold for, which auctions end soon in .com or .ai, which names are about to drop, which keywords people are registering across many endings this week, or the status, last sale and value range of one domain.

Sign in with your DomainToolBelt account and Claude can also manage your own watch list. Watch a domain to get an alert when its owner, nameservers, expiry or status changes, or when it goes to auction or drops. Save domains, add keywords to Keyword Watch and see their latest matches across auctions, drops, names for sale and recorded sales, and read or clear your alerts.

Data comes from DomainToolBelt's own records: reported sales from major marketplaces, auction listings from 20 popular endings, registry drop lists and zone data for 1,400+ endings. Status is the last known state, not a live registrar check, and every answer links to the domain's page on domaintoolbelt.com so you can check before you buy. Value estimates are estimates, not offers.

The free plan returns the top 3 rows of each list. Paid plans return up to 100 rows a page and add the domain status, summary, history and sales tools. Removing a watched domain, a saved domain or a keyword always asks you first.
