# List snapshots for a sandbox



## OpenAPI

````yaml /api-reference/sandboxes.openapi.yaml get /sandboxes/{id}/snapshots
openapi: 3.0.3
info:
  title: Brimble Sandbox API
  description: >
    REST API for managing Brimble sandboxes, ephemeral compute environments with

    optional persistent storage. Covers lifecycle (create / pause / resume /
    destroy),

    egress policy, runtime operations (exec, runCode, file upload/download),

    observability (logs, stats), and snapshots.


    ## Conventions


    - **Response envelope:** non-`204` JSON responses use `{ "message": string,
    "data"?: <payload> }`.
      The schemas below describe the **`data`** payload only.
    - **Errors:** every non-2xx response uses `{ "message": string }`. The
    message is
      user-facing.
    - **Async transitions:** pause / resume / destroy return immediately;
      the status change is visible on the next `GET` or in the dashboard.
      **Create is synchronous** — `POST /sandboxes` blocks until `status` is `ready`.
    - **IDs:** every `id` is a 24-char hex string.
