Arc CLI

Arc CLI connects your Arc account to AI tools like Claude Code, Claude Cowork, and Codex and ask questions about your Arc data in plain English and get answers in seconds using your preferred AI agent.

What Can I Ask?

The Arc CLI enables AI agents to securely access your Arc account data and perform common reporting tasks.

Examples

  • "What's our total available cash?"

  • "What's our current treasury yield?"

  • "Group last month's spend by vendor and export it to CSV."

  • "Download our latest monthly statement."

  • "Show all transactions over $10,000 from the last 30 days."

  • "Summarize our treasury activity this month."

Getting Started

1. Create an API Key

In Arc, navigate to Settings → Developer.

Click Create Key and copy the API key. The key will only be displayed once and will begin with:

arc_sk_

2. Install the Arc CLI

Install the Arc CLI and Arc's AI agent skills:

npm install -g @joinarc/cli && arc skills install

3. Add Your API Key

Run:

arc config add

When prompted, paste your API key.

Why this approach?
arc config add prompts for the key directly, keeping it out of your shell history and out of any AI chat conversations.

4. Start Asking Questions

Open your preferred AI agent and begin asking questions about your Arc data.

If you'd like to verify your setup, run:

arc status
