Extra charge for using Verizon FiOS app or tv streaming app?

Hi everyone, sorry if this was posted about in the past, I couldn't find a previous thread.

I bought an Xbox One a couple of days ago and finally set up the Verizon FiOS app and some other TV streaming services, such as comedy central, ESPN, MTV, and VH1. I have cable services through Verizon FiOS already, but I wanted to make sure that I wouldn't be charged extra for streaming through these apps. I contacted both Xbox and Verizon customer service, but they were both completely useless.

Thanks in advance!
