How to get "Popular" from "Provider"

Hi I wanted to get movie list like from 'https://www.justwatch.com/us'(or https://www.justwatch.com/hk), then i can select providers. With the info from providers I can see what movie or show are currently popular.
Is there anyway to achieve this? I assume i have to how some sort them, but how do i get the list in the first place?

Thanks
