Retrieve an input form the query string

I am trying to get ?limit=50 from my query string reading here:

https://laravel.com/docs/8.x/requests#retrieving-input

my api path: api/todos goes here: App\Http\Controllers\TodoController@index

index method in TodoController

public function index()
    {
        //
        $todos = $this->user->todos()->get(['id', 'title', 'body', 'completed', 'created_by']);
        return response()->json($todos->toArray());
    }

do you want to get 50 items ? then do this

$todos = $this->user->todos()->take(50)->get(['id', 'title', 'body', 'completed', 'created_by']);
OR
$todos = $this->user->todos()->paginate(50);

return response()->json($todos->toArray());

If you are creating an API user Laravel API https://laravel.com/docs/8.x/eloquent-resources#resource-collections technique

You can get query string params using request() helper, passing the key, i.e. request('limit'):

I have expanded the query for clarity

public function index()
{
        $todos = $this->user
		->todos()
		->when(request()->has('limit'), fn ($builder) => $builder->take(request('limit'))
		->get(['id', 'title', 'body', 'completed', 'created_by']);
        return response()->json($todos->toArray());
}

This line when(request()->has('limit'), fn ($builder) => $builder->take(request('limit')) checks for the presence of a limit key on the Request, and then applys the limit on the query; otherwise, there is no limit on the query.
