## OpenClaw API Server 配置

OpenClaw 的 Gateway 可以提供 OpenAI 兼容的 [Fossies](https://fossies.org/linux/openclaw/docs/gateway/openai-http-api.md) Chat Completions 端点，**默认是关闭的**，需要在配置中手动开启。

### 第一步：开启端点

编辑 `~/.openclaw/openclaw.json`，添加：

json

```json
{
  "gateway": {
    "port": 18789,
    "mode": "local",
    "bind": "lan",
    "auth": {
      "mode": "token",
      "token": "fb97035a1b62a4f29e5cb2f9ac131bd37f021a10823f66b0"
    },
    "tailscale": {
      "mode": "off",
      "resetOnExit": false
    },
    "remote": {
      "url": "ws://192.168.3.189:18789"
    },
    "nodes": {
      "denyCommands": [
        "camera.snap",
        "camera.clip",
        "screen.record",
        "contacts.add",
        "calendar.add",
        "reminders.add",
        "sms.send"
      ]
    },
    "controlUi": {
      "allowInsecureAuth": true
    },
    "http": {
      "endpoints": {
        "chatCompletions": {
          "enabled": true
        }
      }
    }
  }
}
```

> `host: "0.0.0.0"` 是为了让 Docker 容器能访问，和 Hermes 同理。

然后重启 Gateway：

bash

```bash
openclaw gateway restart
```

验证：

bash

```bash
curl http://localhost:18789/v1/health
```

## 与 Hermes 的关键区别

|项目|Hermes|OpenClaw|
|---|---|---|
|默认端口|`8642`|**`18789`**|
|Agent 指定方式|`"model": "hermes-agent"`|**`"model": "openclaw:main"`**|
|默认是否开启|✅ 开启|❌ 需手动开启|

OpenClaw 通过 `model` 字段来指定 Agent ID，格式为 `"openclaw:<agentId>"`，例如 `"openclaw:main"` 或 `"openclaw:beta"`。 [OpenClaw AI](https://openclaw-ai.com/en/docs/gateway/openai-http-api/)

## 在 n8n 中调用 OpenClaw

json

```json
{
  "model": "openclaw:main",
  "messages": [
    {"role": "user", "content": "{{ $json.input }}"}
  ]
}
```

| 字段            | 值                                                |
| ------------- | ------------------------------------------------ |
| URL           | `http://192.168.3.189:18789/v1/chat/completions` |
| Authorization | `Bearer your-secret-key`                         |

## 最终架构总结

```
n8n (Docker)
    │
    ├─ POST 192.168.3.189:8642   → Hermes Agent  (port 8642)
    │
    └─ POST 192.168.3.189:18789  → OpenClaw Agent (port 18789)
```

两个都用同一个局域网 IP，只是端口不同，在 n8n 里分别建两个 HTTP Request 节点就可以了。你的 OpenClaw 现在是什么状态，已经安装好了吗？
