No setup needed. Fuse runs Findymail 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 Findymail, in what order, and how to combine the results.

Optional: to use your own Findymail 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.
