# Rollout History

`GET /rollouts/history`

## Request

- Base URL: `https://api.os3robotics.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.os3robotics.com/rollouts/history`
- Auth: one of:
  - HTTP bearer
  - HTTP bearer

Active rollouts plus a page of history by last change, across both kinds.

History defaults to the last 30 days. Use before for older history; X-style next_after
cursors keep tied timestamps and the two kinds in one stable order. Active rollouts stay
visible on every page. A robot_id narrows both lists to that robot of the workspace.

## Query parameters

- `workspace_id` string, uuid, required
- `robot_id` string, uuid, nullable
- `since` string, date-time, nullable
- `before` string, date-time, nullable
- `after` string, nullable
- `limit` integer
