How to get more info from json object (Steam "API")?

Question

Steam

How can I get more information about a subject? I've looked all over the steam api but haven't found anything useful. Need to work with item image and prices but how to get more information in json object ( Best case - image, minimum price and item name )

Is there any documentation what link can go after https://steamcommunity.com/market/
