}

In this example, the API provides a single result:

{
  "count": 1,
  "model_snapshots": [
    {
      "job_id": "farequote",
      "timestamp": 1491948163000,
      "description": "State persisted due to job close at 2017-04-11T15:02:43-0700",
      "snapshot_id": "1491948163",
      "snapshot_doc_count": 1,
      "model_size_stats": {
        "job_id": "farequote",
        "result_type": "model_size_stats",
        "model_bytes": 387594,
        "total_by_field_count": 21,
        "total_over_field_count": 0,
        "total_partition_field_count": 20,
        "bucket_allocation_failures_count": 0,
        "memory_status": "ok",
        "log_time": 1491948163000,
        "timestamp": 1455234600000
      },
      "latest_record_time_stamp": 1455235196000,
      "latest_result_time_stamp": 1455234900000,
      "retain": false
    }
  ]
}
