Create dynamic frontend page / display manager page without login

Is there some frontend controller to create dynamic page with some custom created URL without add them from Manager Resource panel? I want to create some secret page (and perform some actions there) but it shouldn't be seen in Manager for anyone (even admin or myself). I'm pretty newbie in ModX so any direct solutions will be appreciated.

Or... I've custom controller in Manager and I can access it by /manager/?a=some/controller. Is there any way to display it without login user?

you not really want anonymous users have access to the manager?

what kind of actions?

I want to make a connection with external API, distribute content and place them to modx resources. To do that I need some url to place it in connection parameteres. But this page cannot be visibile anywhere to avoid user from delete it or something unexpected. So resume your questions:

1. I want to insert resources from external API (as an author I need some user ID, for now i dont know if it will be always userID = 1 or some other ID) so i need access to manager or frontend secret page to do "magic things".

2. These actions are inserting / editing / deleting resources provided from my external API.

you might want to have a look, how bezumkin it does, for his mxManager

You might also look at NewsPublisher. The latest version has a delete button in addition to creating and editing resources.
