# Anthropic (Claude)

Anthropic builds the **Claude** model family and provides access via an API.
In Clawdbot you can authenticate with an API key or reuse **Claude Code / Claude CLI**
credentials (setup-token or OAuth).

## Option A: Anthropic API key

**Best for:** standard API access and usage-based billing.
Create your API key in the Anthropic Console.

### CLI setup

```bash
clawdbot onboard
# choose: Anthropic API key

# or non-interactive
clawdbot onboard --anthropic-api-key "$ANTHROPIC_API_KEY"
```

### Config snippet

```json5
{
  env: { ANTHROPIC_API_KEY: "sk-ant-..." },
  agents: { defaults: { model: { primary: "anthropic/claude-opus-4-5" } } }
}
```

## Option B: Claude CLI (setup-token or OAuth)

**Best for:** using your Claude subscription or existing Claude CLI login.

### CLI setup

```bash
# Run setup-token on the gateway host (wizard can run it for you)
clawdbot onboard --auth-choice setup-token

# Reuse Claude CLI OAuth credentials if already logged in
clawdbot onboard --auth-choice claude-cli
```

### Config snippet

```json5
{
  agents: { defaults: { model: { primary: "anthropic/claude-opus-4-5" } } }
}
```

## Notes

- The wizard can run `claude setup-token` on the gateway host and store the token.
- Auth details + reuse rules are in [/concepts/oauth](/concepts/oauth).
