PPro cloud could be use as a service to modify some files from remote?

For example (ordered by simplicity)

Modify the pitch of the audio 
Modify the pitch of the audio without afecting video fullfilling with silence to mantain the original duration.
Modify the pitch of the audio and video but adding black frames to mantain the original duration.
Apply some adjust.

Its is that posible use PPro cloud to do that?

How? Where I need to run my code? Is Windows mandatory?

What I need learn? Extendscrip? c++? There is something like this for ruby?

What other ways I have?

Thanks and sorry for my super extended question.
