Set Up Claude Code for OpenClaw

Connect your Claude Pro subscription to OpenClaw using Claude Code. Step-by-step for Mac and Windows.

OpenClaw uses Claude as its AI engine. To make your assistant work, you need to connect your Claude Pro subscription using Claude Code.

Do NOT use the Anthropic API

OpenClaw does not use the classic Anthropic API from platform.claude.com. That's pay-per-token and costs a lot more than a Claude subscription.

Step 1 — Subscribe to Claude Pro

Go to claude.ai/pricing and subscribe to Claude Pro ($20/month) or Claude Max ($100-200/month).

Once your subscription is active, you can install Claude Code to get your API key.

Step 2 — Install Claude Code

Claude Code is the official tool that lets OpenClaw use your Claude subscription.

On Mac — open a terminal and run:

bash
curl -fsSL https://claude.ai/install.sh | bash

Don't know how to open a terminal?

Open Spotlight (Cmd+Space), type "Terminal", and press Enter.

On Windows — open a terminal and run:

bash
curl -fsSL https://claude.ai/install.cmd -o install.cmd && install.cmd && del install.cmd

Step 3 — Generate your token

In your terminal, run:

bash
claude setup-token

Claude will open a login page in your browser.

Claude Code authorization page

Log in with your Claude account and accept. Claude Code will generate an access token linked to your subscription. It looks like this:

sk-ant-xxxxxxxxxxxxxxxx

Copy this token — you'll paste it into your OpenClaw configuration as ANTHROPIC_API_KEY.

Common mistakes

Never create an API key on platform.claude.com

The Anthropic developer console (platform.claude.com) is for developers building apps with the API. It charges per token and is much more expensive than using your Claude Pro subscription through Claude Code.

Disable Extra Usage immediately

In your Claude account settings, find the option "Turn on extra usage to keep using Claude if you hit a limit" and make sure it is unchecked. If you leave it on, you may get surprise charges when you exceed your plan limits.

If you need more capacity, upgrade to Claude Max instead.
