# Usage Activity

GET https://api.onepin.ai/api/v1/usage/activity

Return the workspace activity feed as a cursor-paginated event list.

Each item represents a discrete workspace event (workflow run, voice generated,
template applied, member invited, API key created, settings changed). Events are
ordered newest-first within the requested rolling window.

Filtering:
- `type` narrows to a single action kind (e.g. `workflow_run`).
- `user_id` restricts to events triggered by a specific workspace member;
  returns 404 if the user is not a member of this workspace.
- Both filters can be combined.

Pagination: pass the `cursor` value from a previous response to retrieve the
next page. An absent or null `cursor` in the response means no further pages
exist. Page size is controlled by `limit` (1–100, default 20).

Date boundaries are computed in the supplied `timezone` (IANA). Defaults to UTC.

Dual-auth: Bearer JWT or API key (scope `workspace:read`).
