There is no way to get current values from config, not with python API, not with HTTP API, no way...
curl -X POST -F data='{"op": "show", "path": ["noc"]}' -F key=qwerty http://10.255.56.5:8080/configure {"success": false, "error": "\"show\" is not a valid operation", "data": null}
PLZ! Add this opportunity!
