Buying a phone number is procurement, and procurement UI is where products usually give up. Search, capability and cost are on one screen, and what it will bill you is stated before you commit rather than after.
Numbers get burned. Reputation is a column in the inventory, where you are already looking. A flagged number is visibly flagged, with rotating it available in the same row.
Twilio runs underneath all of it. Search, purchase, capability and billing are hooked straight through, so the inventory on screen is the inventory that exists rather than a copy of it that has to be kept in step.
