capit 0.3.0

Issue authentication keys with spending caps

Budget per-agent, per-provider, as little or as much as you want

$ uvx capit openrouter 5.00 --agent openclaw -y
$5.00 openrouter key installed into openclaw

That's it. Openclaw now has a capped API key. If it goes rogue, it can only cost you $5.

Install

uvx install capit

Usage

Give an agent a budget

# Claude Code - $5 cap
capit openrouter 5.00 --agent claude -y

# Cursor - $10 cap
capit openrouter 10.00 --agent cursor -y

# Windsurf - $5 cap
capit openrouter 5.00 --agent windsurf -y

# OpenClaw - $5 cap
capit openrouter 5.00 --agent openclaw -y

Each agent gets its own capped key. Sleep soundly.

More agents

capit --consumers  # List all supported agents

See consumers/README.md for the full list and adding custom agents.

First time?

capit openrouter 5.00 --agent claude -i -y

The -i flag prompts for your OpenRouter management key once. It's used to create the capped key, then discarded.

---

Platforms

The included platforms are openrouter and unkey.

Platforms are easy to create with a claude skill located in skills/platform-creator.md.

See platforms/README.md for more details.

Administration

capit --keys list              # Your master keys
capit --keys list -r openrouter  # Capped keys created on OpenRouter
capit --keys delete openrouter <id>  # Revoke a key
capit --platforms              # Available platforms
capit --consumers              # Supported agents

How It Works

1. You run capit openrouter 5.00 --agent claude -y
2. capit calls OpenRouter's API
3. capit creates a guardrail with $5 cap
4. capit creates an API key with that guardrail
5. capit writes the key to ~/.claude/.credentials.json
6. Done

The cap is enforced by OpenRouter. The key literally cannot spend more than $5.
