They used the http://subapi.com/ website as a gateway between their app and http://yts.re/api. You can browse precedent commits to check the previous code, which is what I'm doing now.
Popcorn Time 0.1.0 depends on subapi.com to continue functioning. Based on the source the API returns JSON file with the following structure: { movies: { [ torrents: [ {'quality': '1080p', url: 'http://url.torrent'}, {'quality': '720p', url: 'http://url.torrent'}, {'quality': 'undefined', url: 'http://url.torrent'} ], subtitles: [ {'language': 'en', url: 'http://url.srt'}, {'language': 'undefined', url: 'http://url.srt'} ], imdb_id:, title:, year:, runtime:, synopsis:, voteAverage:, poster:, backdrop:, seeders:, leechers: ] } }
I know they took the down the download link. People are reporting the app no longer works.
