Every 6th hour a list of data of all content from SVTPlay is backed up in ./singles_and_episodes.json.xz file. All available title page data is also stored in ./title_pages.json.xz. I made this mostly just for fun but it can be useful for retrieving information that is no longer available on SVTPlay.
Extract archives using the xz command:
xz -dk singles_and_episodes.json.xz
xz -dk title_pages.json.xz
The code used to acquire this data is located in ./src.
