Sharing same route with unauthenticated and authenticated users in Laravel 5.3

I have a route that where I'm using an auth middleware and it works great.

Route::group(['prefix' => 'v1','middleware' => ['auth:api']], function()
{
  Route::resource('user', 'v1\MyController');
});

The problem is that I would also like this route to be accessible to non-authenticated users as well. With the above, I get a 401 Unauthorized error and I can't return any content for unauthenticated users. So how can I authenticate this route (so it passes down the user data) while also allowing the route to proceed even if the user is NOT authenticated?

(I tried doing a conditional Auth check on the router page but it seems the user has gone through authentication yet so it always remains false.)
