Simple roblox api not printing what i expected?

Using http://wiki.roblox.com/index.php?title=Web_APIs as a reference to get the name and other stats of an asset you should use https://api.roblox.com/Marketplace/ProductInfo?assetId=id

I used another api to get the thumbnail of a game but how would i be able to turn this into a table as shown in the wiki because if i try to print it then it just returns the url link
