Commands

Data Source

Token Lens reads usage data from the local Kilo SQLite database and your z.ai account quota via the z.ai API. The database location defaults to $XDG_DATA_HOME/kilo/kilo.db (~/.local/share/kilo/kilo.db, or %LOCALAPPDATA%\kilo\kilo.db on Windows) and can be changed via the token-lens.databasePath setting or the in-sidebar settings panel.

Getting Started

1. Install the extension from the VS Code Marketplace
2. Open the Command Palette (Ctrl+Shift+P / Cmd+Shift+P)
3. Run TokenLens: Set API Key and paste your z.ai API key
4. Token usage appears in the status bar immediately
