Laravel 5.7 multiple authentication api route problem

Firstly hi all and sorry my poor english.

I have a problem on my laravel project.

I have multiple authentication on my laravel project. And also I have 3 guards. Login screens works perfecly with web.php.

I just want to write an api resource. I want to if any user logined to system with web,sube_admin and admin guards return an result; this api must be accessible for all users.

Firstly i'm logined with admin guard.

If I write this in to web.php

Route::middleware('auth_api_json:admin,sube_admin,web')->group(function(){
    Route::get('/iller', function (Request $request) {

        dd(auth()->guard("admin")->check());

    });

});

And if I go to localhost:8000/iller address, this code is returns true.

If I write bellow code on my api.php file

Route::middleware('auth_api_json:admin,sube_admin,web')->group(function(){
    Route::get('/iller', function (Request $request) {

        dd(auth()->guard("admin")->check());

    });

});

I need to go now to localhost:8000/api/iller address, after that I see in my results is false.

I just want to write my code perfectly, I want to use my api.php file and I want to use /api/ on my address bar.

And here is my auth_api_json Middleware file source.

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Auth\Middleware\Authenticate as Middleware;

class Api extends Middleware
{

}

laravel / framework
