The closest you can get it is

```
[
	{
		"name": "node_name",
		"ram.percent": "58"
	}
]

```

by accessing [http://localhost:9200/\_cat/nodes?h=name,ram.percent&format=json](http://localhost:9200/_cat/nodes?h=name,ram.percent&format=json)

You can always get the cluster details which will contain the number of nodes by accessing [http://localhost:9200/\_cluster/health](http://localhost:9200/_cluster/health)

```
{
  "cluster_name" : "testcluster",
  "status" : "yellow",
  "timed_out" : false,
  "number_of_nodes" : 1,
  "number_of_data_nodes" : 1,
  "active_primary_shards" : 5,
  "active_shards" : 5,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 5,
  "delayed_unassigned_shards": 0,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch": 0,
  "task_max_waiting_in_queue_millis": 0,
  "active_shards_percent_as_number": 50.0
}
```
