Get steam item prices

Question

I was wondering if there is any efficient way to get the prices of an item on steam. I found :

http://steamcommunity.com/market/priceoverview/?country=DE&currency=3&appid=730&market_hash_name=P90%20%7C%20Asiimov%20%28Factory%20New%29

You get JSON with only "lowest_price". How I can get JSON with 3 lowest prices ?

Solution

I use

render?start=0&count=10&currency=3&language=english&format=json

currency: 1 for USD, 2 for GBP, 3 for EUR, 5 for RUB
