The repository describes a monochrome month-to-date dashboard that wakes the device on scheduled RTC slots, refreshes over Wi-Fi, then suspends while the e-ink screen retains the image.
The Node.js server aggregates daily usage from local collectors and imports. Listed sources include Codex, Claude Code, OpenCode, Gemini CLI, Cursor, Claude API, GitHub Copilot and Gemini ledgers. The display reports token totals and an API-equivalent list-price estimate, rather than the cost of a subscription. Collectors send only a daily date, canonical agent, token total and USD estimate to the server.
The project requires Node.js 20+ and a machine that remains awake for refresh windows. Its Kindle runtime uses FBInk, Wi-Fi refreshes and suspend-to-RAM; the Kindle must have a reachable private-LAN address, since a stock device cannot join a Tailnet. The repository includes a reusable skill for checking jailbreak compatibility and configuring the setup. It does not establish that every Kindle model or firmware is supported, nor that its estimates match a user's actual subscription charges.
