# ![NEAR AI Cloud ロゴ](https://models.dev/logos/nearai.svg)NEAR AI Cloud

Mastra のモデルルーターを通じて 37 個の NEAR AI Cloud モデルを利用できます。認証には `NEARAI_API_KEY` 環境変数が自動的に使用されます。

詳しくは、[NEAR AI Cloud のドキュメント](https://docs.near.ai/)を参照してください。

```bash
NEARAI_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: "nearai/Qwen/Qwen3-30B-A3B-Instruct-2507"
});

// 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);
}
```

> **情報:** Mastra は OpenAI 互換の `/chat/completions` endpoint を使用します。一部の Provider 固有機能は利用できない場合があります。詳しくは、[NEAR AI Cloud のドキュメント](https://docs.near.ai/)を確認してください。

## 高度な設定

### カスタムヘッダー

```typescript
const agent = new Agent({
  id: "custom-agent",
  name: "custom-agent",
  model: {
    url: "https://cloud-api.near.ai/v1",
    id: "nearai/Qwen/Qwen3-30B-A3B-Instruct-2507",
    apiKey: process.env.NEARAI_API_KEY,
    headers: {
      "X-Custom-Header": "value"
    }
  }
});
```

### 動的なモデル選択

```typescript
const agent = new Agent({
  id: "dynamic-agent",
  name: "Dynamic Agent",
  model: ({ requestContext }) => {
    const useAdvanced = requestContext.task === "complex";
    return useAdvanced
      ? "nearai/zai-org/GLM-5.1-FP8"
      : "nearai/Qwen/Qwen3-30B-A3B-Instruct-2507";
  }
});
```
