What features of the VK API can be used without authorization by the user?

Question

Android

Good day.
There was a need to use the capabilities of api vkontakte, but I can’t understand what features are available if you don’t ask the user to give permission to the application? Most of all, I'm interested in the usual search for music and, accordingly, its transfer (to the android application). And what procedures do I need to go through before VK gives me the right to use them? More precisely, what OAuth authorization do I need to use if each application client will use VK music search?
Thank you very much for your help.
