Put Route returns CSRF token mismatch Laravel

I am trying to configure a crud api for a blog and right now i made the PostController like this:

<?php

namespace AppHttpControllers;

use AppModelsPost;
use AppHttpRequestsStorePostRequest;
use IlluminateHttpRequest;

class PostController extends Controller
{
    /**
     * Display a listing of the resource.
     */
    public function index()
    {
        $posts = Post::all();
        return response()->json([
            'posts' => $posts
        ]);
    }

    /**
     * Store a newly created resource in storage.
     */
    public function store(StorePostRequest $request)
    {
        $post = Post::create($request->all());

        return response()->json([
            'message' => "Post Created successfully!",
            'post' => $post
        ], 200);
    }

    /**
     * Display the specified resource.
     */
    public function show(Post $post)
    {
        //
    }

    /**
     * Show the form for editing the specified resource.
     */
    public function edit(Post $post)
    {
        //
    }

    /**
     * Update the specified resource in storage.
     */
    public function update(StorePostRequest $request, Post $post)
    {
        $post->update($request->all());

        return response()->json([
            'message' => "Post Updated successfully!",
            'post' => $post
        ], 200);
    }

    /**
     * Remove the specified resource from storage.
     */
    public function destroy(Post $post)
    {
        $post->delete();

        return response()->json([
            'status' => true,
            'message' => "Post Deleted successfully!",
        ], 200);
    }
}

and web.php is this one:

<?php

use IlluminateSupportFacadesRoute;
use AppHttpControllersPostController;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider and all of them will
| be assigned to the "web" middleware group. Make something great!
|
*/

Route::get('/', function () {
    return view('welcome');
});

Route::resource('posts', PostController::class);

and when i try to use postman
http://127.0.0.1:8000/posts/ works and shows me all the data but nothing else
And yes i switched the GET with POST and even tried with PUT
and i get the following:

 "message": "CSRF token mismatch.",

I do not have any front-end in this project to put that csrf field there, how should i solve this?
