Start here
Let your coding agent wire TokenPolice for you, or do it by hand in Python or Node — both paths start with an API key.
Adding TokenPolice means installing an SDK, initializing it at startup, and wrapping the code that handles one run. There are two ways to get there.
The fast way: let your coding agent do it
If you code with Claude Code, Cursor, Copilot, Antigravity, or Codex, install the TokenPolice skill once and ask your agent to integrate. It reads your repo, asks you a short batch of questions, shows you a plan, makes the edits, and then proves the integration actually works before it calls it done. You write no integration code.
Or wire it by hand
It's a small integration — install, init(), wrap your entrypoint — and doing it yourself
means you see every line. Pick your language:
Manual setup — Python
pip install, tp.init(), @tp.workflow. About one screen.
Manual setup — Node
npm i, tp.init() with instrumentModules, tp.workflow. About one screen.
Those two pages get you metering. When you're ready to do the whole job properly — identity threading, tool spans, flushing, error handling, and actually verifying it works — follow the same checklist the skill does:
Either way, start with a key
Both paths need the same two things: an API key and the collector URL. Get them once and you're ready for either.
