Laravel API

Hello,

This is Laravel API. I never used Laravel API before, I have tried using CI API.

BannerController.php

public function listBanner() {
        $today = date("Y-m-d");
        $banner = BannerModel::where('status', '1')
                            ->where('expire_date', '>', $today)
                            ->get();


        return response()->json(array(
            'status' => 200,
            'message'=> 'Banner listed',
            'data'=> $banner,
            'path_banner' => asset('/banners') 
        ), 200);
    }

I wonder how do you call the API since it is in Json format. Any idea? I also wonder why the API is not in it's own server. This one is united with the front end.

Thanks in advance.
