FAQ
How does it track Anthropic API usage?
With an Anthropic Admin API key, which requires an Anthropic organization. T4B uses that key to read your organization's API spend. Claude Code is a separate connection: it reads Claude Code's local session files, so it needs no key.
Does it track direct API calls made outside Claude Code?
Yes, when you connect the Anthropic API with an Admin API key, because that reports your organization's API spend rather than only Claude Code. Without an Admin key, T4B covers what runs through Claude Code via its local logs. The Anthropic Console remains your billing source of truth.
Is any of this sent to a server?
Your usage data stays on your Mac and there is no account. To fetch Anthropic API spend, the app calls Anthropic's API with your Admin key; Claude Code logs are read locally. The built-in audit log shows that network activity.
