curl -X POST https://projecthollow.com/monitoring/ingest/v1/monitors \
  -H "Authorization: Bearer hlw_sk_…" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: checkout-uptime-check" \

For synthetic browser monitors ({"type": "browser"}), supply a steps array (up to 20 steps per monitor). Each step specifies kind (click, fill, wait_for, or assert_text), a DOM selector string, optional text value, and optional timeoutMs (default 10,000 ms).

Fetch all active monitors configured for your developer key owner.

  "monitors": [
    { "id": "mon_123", "name": "Checkout API Uptime", "type": "http", "target": "https://checkout.example.com/health", "status": "up", "intervalMinutes": 5 }
  ]
}
