Phone intelligence and contact verification: line type, carrier, activity score, caller identity, reverse phone lookup, and name/phone/email match-grading (US-focused).
What it does
Use Trestle in Fuse to:
Check phone line type, carrier and activity score
Identify callers and reverse-look up phone numbers
Grade how well a name, phone and email match (US-focused)
Setup
No setup needed. Fuse runs Trestle on its own account and bills each successful step to your credit balance.
Describe what you need to Fuse Deep Research in plain language. The agent decides when to call Trestle, in what order, and how to combine the results.
Optional: to use your own Trestle key instead, open Settings → Provider Keys in the Fuse app (workspace owners and admins), add the key and save. Fuse checks it straight away, and your key is only used for your own runs.
