- GET /analytics/errors - Get error reports
- GET /analytics/performance - Get performance metrics
- GET /analytics/export - Export analytics data
- GET /workflows/{execution_id}/status - Get workflow status
- POST /workflows/{execution_id}/pause - Pause workflow
- POST /workflows/{execution_id}/resume - Resume workflow
- POST /workflows/{execution_id}/cancel - Cancel workflow
- Authentication/authorization
- Analytics queries
- Workflow control
- Export formats
