# Expose Sandbox Port

> Creates or returns public access to a TCP port in the sandbox.



## OpenAPI

````yaml PUT /api/sandboxes/{sid}/ports/{port}
openapi: 3.1.0
info:
  title: Archil Control Plane API
  description: >
    The Archil Control Plane API provides programmatic access to manage disks,

    persistent sandboxes, mounts, and API keys in the Archil distributed

    filesystem platform.


    API keys authenticate requests to this control plane and are scoped to

    your account. They are distinct from *disk tokens*, which are per-disk

    credentials used by clients when mounting a disk.


    ## Authentication


    All endpoints require an API key:


    ```

    Authorization: {API_KEY}

    ```


    Create API keys in the [Archil Console](https://console.archil.com) or via
    the API.


    ## Response Format


    All responses use a consistent envelope:


    ```json

    {
      "success": true,
      "data": { ... }
    }

    ```


    Or on error:


    ```json

    {
      "success": false,
      "error": "Error message"
    }

    ```
