# 서버리스 샌드박스 시작하기

> W&B API 키로 첫 서버리스 샌드박스를 실행해 보세요.

Run a command in a serverless sandbox and print its output. No cluster setup is required.

## Run your first sandbox

<span id="choose-a-credential" />

<span id="run-a-sandbox-on-serverless-capacity" />

[W\&B API 키](https://forge.coreweave.com/settings#apikeys)를 발급받으세요. 계정이 없다면 같은 링크에서 가입할 수 있습니다. 그런 다음 터미널에서 키를 설정하세요.

```bash theme={"system"}
export WANDB_API_KEY="[WANDB-API-KEY]"
```

<Tabs>
  <Tab title="Python">
    [`uv`](https://docs.astral.sh/uv/getting-started/installation/)를 설치한 상태에서 다음 코드를 `hello.py`로 저장하세요:

    ```python title="hello.py" theme={"system"}
    from cwsandbox import AuthStrategy, Sandbox

    with Sandbox.run(
        auth=AuthStrategy.WANDB,
        resources={"cpu": "1", "memory": "1Gi"},
    ) as sandbox:
        print(sandbox.exec(["echo", "Hello!"]).result().stdout)
    ```

    Python 3.11과 샌드박스 클라이언트로 실행하세요. 둘 다 필요하면 다음 명령어가 자동으로 설치합니다:

    ```bash theme={"system"}
    uv run --python 3.11 --with 'cwsandbox[wandb]>=1.10.0' hello.py
    ```
  </Tab>

  <Tab title="TypeScript">
    Node.js 22 이상을 설치한 상태에서 클라이언트를 설치하세요:

    ```bash theme={"system"}
    npm install @coreweave/cwsandbox
    ```

    다음 코드를 `hello.mts`로 저장하세요:

    ```typescript title="hello.mts" theme={"system"}
    import { createSandboxClientFromEnv } from "@coreweave/cwsandbox/wandb";

    const client = createSandboxClientFromEnv();
    const result = await client.withSandbox(
      async (sandbox) => sandbox.commands.run(["echo", "Hello!"]),
      { resources: { cpu: "1", memory: "1Gi" } },
    );
    console.log(result.stdout);
    ```

    `tsx`로 실행하세요:

    ```bash theme={"system"}
    npx --yes --package=tsx tsx hello.mts
    ```
  </Tab>
</Tabs>

이 예시는 [wandb.ai](https://wandb.ai)에서 발급받은 키를 사용합니다.

The example prints the following output and stops the sandbox when it finishes:

```text title="Output" theme={"system"}
Hello!
```

The sandbox has 1 CPU and 1 GiB of memory. Serverless sets resource limits equal to requests. Change `resources` to choose its CPU and memory.

For concurrent quotas, rate limits on create requests, and quota errors, see [Limits and quotas](reference/limits-and-quotas).

<Note>
  Serverless Sandboxes is generally available, and usage is billed. Access is enabled per organization. To request access for your organization, contact [support](mailto:forge-support@coreweave.com).

Continue with the guide for your workload:

* [Run coding agents](agents): connect a coding agent to a sandbox.
* [GPU sandboxes](gpu-sandboxes): request GPU access and run a GPU workload.
* [Python client](/products/sandboxes/client): execute commands, work with files, and configure sandboxes.
