Example from https://status.defenseorchestrator.com/api/v2/summary.json:

{
    "page": {
        "id": "mq1rp1pdj1mv",
        "name": "Cisco - Cisco Defense Orchestrator",
        "url": "https://status.defenseorchestrator.com",
        "time_zone": "Etc/UTC",
        "updated_at": "2021-11-08T20:44:48.949Z"
    },
    "components": [],
    "incidents": [],
    "scheduled_maintenances": [],
    "status": {
        "indicator": "none",
        "description": "All Systems Operational"
    }
}
