HBO Go is now available on the Xbox One. The app gives you access to all of HBO's movies and series, all in a brand-new package for the Xbox One. Just select a category from the sidebar menu, and you're off.
To activate HBO Go, you'll need to go to HBO's activation website and enter the code that the Xbox app gives you. Importantly, the Xbox One is not listed as one of the compatible devices. Select Xbox 360, then enter your code, and you should be all set. HBO Go does, of course, require an HBO subscription through your cable provider.
