Claude API keys typically look like: 
sk-ant-xxxx...
Keep this key private. Anyone with the key can use your Anthropic account and consume usage.

​
Step 2: Open your Agent 37 instance

  1. Go to the Agent 37 dashboard and sign in.
  2. Open an existing instance, or create a new one.
  3. Open Terminal.

​
Step 3: Configure OpenClaw to use Anthropic

In Terminal, run: 
openclaw configure
When prompted, choose the following:
  1. Where will the gateway run? → Local
    Image
  2. Select Section to Configure? → Mode
    Image
  3. Model / Auth Provider → Anthropic
    Image
  4. Anthropic Auth Model → Anthropic API Key
    Image
  5. How do you want to provide this API key now? → Paste API key now
    Image
  6. Enter Anthropic API key → paste the key you copied in Step 1
    Image
  7. Models in /models picker → choose the model you want to use, for example anthropic/claude-sonnet-4-6
    Image
  8. After selecting the model, choose Continue
Image
If you are not sure which model to choose, start with a Claude Sonnet model. It is usually a strong default for general OpenClaw workflows.

​
Step 4: Verify the configured model

Run: 
openclaw models list
You should see the model you selected marked as the default in the output.
