Mastra의 Model 라우터를 통해 20개의 AgentRouter Model에 액세스하세요. 인증은 다음을 사용하여 자동으로 처리됩니다.`AGENTROUTER_API_KEY` environment variable.

자세한 내용은 다음에서 확인하세요.[AgentRouter documentation](https://docs.agentrouter.org).

```bash
AGENTROUTER_API_KEY=your-api-key
```

```typescript
import { Agent } from "@mastra/core/agent";

const agent = new Agent({
  id: "my-agent",
  name: "My Agent",
  instructions: "You are a helpful assistant",
  model: "agentrouter/claude-3-5-haiku-20241022"
});

// Generate a response
const response = await agent.generate("Hello!");

// Stream a response
const stream = await agent.stream("Tell me a story");
for await (const chunk of stream) {
  console.log(chunk);
}
```

## 고급 구성

### 맞춤 헤더

```typescript
const agent = new Agent({
  id: "custom-agent",
  name: "custom-agent",
  model: {
    url: "https://agentrouter.org/v1",
    id: "agentrouter/claude-3-5-haiku-20241022",
    apiKey: process.env.AGENTROUTER_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
      ? "agentrouter/kimi-k2-thinking"
      : "agentrouter/claude-3-5-haiku-20241022";
  }
});
