VK.api how is this implemented?

Question

In contact with

In a bunch of VK applications, a player is implemented and works just with VK.api audio in Iframe such as https://vk.com/app5648811_55818031 , https://vk.com/app5124367 , https://vk.com/app3144697 , https ://vk.com/app4333086 , https://vk.com/app4397521 And they just pull the music by calling api.vk, which is visible on the console It's

not clear how this action happens when audio.API is publicly closed!!! How can this be implemented in Iframe VK? And as you can see, everything is without any crutches!
