Activation-limited API key proxy. Give AI agents exactly the access they need, and nothing more.
Create proxy keys with a hard activation limit. 500 calls, then it's dead. No math required.
Agents use scoped keys exactly like real API keys. Just change the base URL. Supports streaming.
See every key's activation count in real time. Create, monitor, and revoke from one screen.
Optional per-key IP restrictions. Lock a key to a specific machine or subnet.
SQLite atomic increment + header swap. 1-3ms total, negligible vs LLM inference time.
Single binary, embedded SQLite, zero external dependencies. Docker, npx, or bare metal.
Every other approach makes you do homework. Activations are the simplest possible limit.
From Old English "til" (meaning "until"). A cash register where you make a withdrawal. A temporal limit on access. Your keys work till they don't.
