# 代码示例

以下示例使用 Lazu 托管版 Base URL。自部署时，请替换成你自己的 API 域名。

## OpenAI 兼容对话

### Python

```python
from openai import OpenAI

client = OpenAI(
    base_url="https://api.lazu.ai/v1",
    api_key="YOUR_LAZU_KEY",
)

response = client.chat.completions.create(
    model="gpt-6-luna",
    messages=[
        {"role": "system", "content": "你是一个有帮助的助手。"},
        {"role": "user", "content": "用一段话解释模型路由。"},
    ],
)

print(response.choices[0].message.content)
```

### JavaScript

```javascript
import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://api.lazu.ai/v1",
  apiKey: process.env.LAZU_API_KEY,
});

const response = await client.chat.completions.create({
  model: "gpt-6-luna",
  messages: [{ role: "user", content: "Hello from Lazu" }],
});

console.log(response.choices[0].message.content);
```

## 流式响应

```python
stream = client.chat.completions.create(
    model="claude-sonnet-5",
    messages=[{"role": "user", "content": "写一份简短部署 checklist。"}],
    stream=True,
)

for chunk in stream:
    delta = chunk.choices[0].delta.content
    if delta:
        print(delta, end="", flush=True)
```

## 模型发现

```bash
curl https://api.lazu.ai/api/models/catalog \
  -H "Authorization: Bearer YOUR_LAZU_KEY"
```

> 用 catalog 响应决定 endpoint、模态和参数。不要在 Agent 或 SDK wrapper
> 里硬编码全局模型列表。
