Data mining

i am an app developer, building my own app for android, which provide all information(images, rating, videos, ...etc) for PlayStation games by using IGDB API, unfortunately this API not provide the games price, so i tried to use google custom search API, since it provide JSON response , but i couldn't get accurate results. so i am looking for solution that when i provide the game's name inside my app it give me the precise price for that game from the official PlayStation site [login to view URL] Note: that i have to execute this process from my app code, so it has to be some format that i can deal with like (Get http://) request that return JSON response .
