Returning pagination data as model collection

Is there a way to get pagination data inside collection?

return response()->
json(
    User::with(['posts' => function($q) {
        $q->paginate(5);
    }, 'posts.comments' => function($q) {
        $q->paginate(5, ['*'], 'commentsPage', request('commentsPage'));
    }])
    ->where('username', request('username'))
    ->firstOrFail()
);

I need to pass this as well: $q->nextPageUrl() for posts
