How to send variable/function from Model to Controller in Laravel?

My goal is to create a model, function(s), so I can reuse them throughout my application. I started by creating a model

Network.php

<?php
namespace App;

class Network extends Model {

    public function scopeVCPE($attr){

        $vcpes_get = shell_exec('curl http://ift.tt/1LXh9TW');
        $vcpes_raw = json_decode($vcpes_get,true);
        $vcpes_array =  $vcpes_raw['data'][0];
        //         "cpe_mac": "1234567890",
        //         "max_up": 300000,
        //         "max_down": 500000,
        //         "filter_icmp_inbound": true,
        //         "dmz_enabled": false,
        //         "dmz_host": "http:\/\/ddd.com",
        //         "vlan_id": 2,
        //         "dns": ["8.8.8.8", "4.2.2.1"],
        //         "xdns_mode": 0,
        //         "cfprofileid": 11111,
        //         "stub_response": "",
        //         "acl_mode": 1,
        //         "portal_url": "http:\/\/portal.com",
        //         "cpe_max_up": 1000000,
        //         "cpe_max_down": 2000000,
        //         "cpe_guaranty_up": 300000,
        //         "cpe_guaranty_down": 400000,
        //         "account_id": 1234,
        //         "location_id": 3333,
        //         "network_count": 3,
        //         "group_name": "test_group",
        //         "vse_id": 20,
        //         "firewall_enabled": false

        return $vcpes_array[$attr];

    }


}

On top of my controller, I include that model use App\Network;

---

Use it

Network::scopeVCPE('cpe_mac');

I tried dd(Network::scopeVCPE('cpe_mac'))

I was hoping to get this result of my cpe_mac : 1234567890

---

Result

Class 'App\Network' not found

I am a little stuck now. Any helps on this will be much appreciated.

Am I forgot to do anything ?
