Apply a usage charge from the job file

I want to apply usage charges from the Job file. I have referred to this documentation, but I can't find a way to run this URL from the job file.

# App/Http/Controllers/Example
# ...
public function index()
{
    // Description and price of usage charge (the only two parameters required)
    $charge = [
        'description' => 'Five e-mails',
        'price'       => 1.00,
        'redirect'    => route('example.success') // Optional, if not supplied redirect goes back to previous page with flash `success`=`true`
    ];

    // Create a signature to prevent tampering
    $signature = createHmac(['data' => $charge, 'buildQuery' => true], Config::get('shopify-app.api_secret'));

    // Create the route
    $usageChargeRoute = route('billing.usage_charge', array_merge($charge, ['signature' => $signature]));

    return view('example.index', compact('usageChargeRoute'));

<a href="{{ $usageChargeRoute }}">Add more emails!</a>
