- `$WORKSPACE_ID`: The workspace ID of the task to be paused, passed through the `X-Workspace-ID` Header.
- `$TASK_ID`: ID of the task to be suspended.

## Request example

```bash
curl -X POST "https://moi.matrixorigin.cn/newmoi/task/pause" \
  -H "X-API-Key: $AI_STUDIO_API_KEY" \
  -H "X-Workspace-ID: $WORKSPACE_ID" \
  -H 'Content-Type: application/json' \

```
