## 고급 구성

### 맞춤 헤더

```typescript
const agent = new Agent({
  id: "custom-agent",
  name: "custom-agent",
  model: {
    url: "https://router.requesty.ai/v1",
    id: "requesty/claude-fable-5",
    apiKey: process.env.REQUESTY_API_KEY,
    headers: {
      "X-Custom-Header": "value"
    }
  }
});
```

### 동적 Model 선택

```typescript
const agent = new Agent({
  id: "dynamic-agent",
  name: "Dynamic Agent",
  model: ({ requestContext }) => {
    const useAdvanced = requestContext.task === "complex";
    return useAdvanced
      ? "requesty/o4-mini@eu"
      : "requesty/claude-fable-5";
  }
});
```
