Claude API keys typically look like:

```text theme={null}
sk-ant-xxxx...
```

<Warning>
  Keep this key private. Anyone with the key can use your Anthropic account and consume usage.
</Warning>

## Step 2: Open your Agent 37 instance

1. Go to the [Agent 37 dashboard](https://www.agent37.com/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:

```bash theme={null}
openclaw configure
```

When prompted, choose the following:

1. **Where will the gateway run?** → `Local`

</Frame>

<Tip>
  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.
</Tip>

## Step 4: Verify the configured model

Run:

```bash theme={null}
openclaw models list
```

You should see the model you selected marked as the default in the output.
