To get the list of all schemas registered in the db:

Method : GET

URI : /stream/list

Example

curl -X GET http://192.168.1.105:18080/stream/list

Response

{
   "errcode":0,
   "num_schemas":1,
   "schemas":[
      {
         "name":"ecomm",
         "state":1,
         "num_streams":1
      }
   ],
   "notif_count_total":0,
   "notif_count_day":0,
   "notif_count_prev_day":0
}

As you note, it returns list of schemas and their streams, apart from some more important info around notifications.
