Does this still occur?
I'm using your api to get the most current prices for a website i'm currently developing.
Everything works quite well, but i get the wrong Quantity for 1 Item:Operation Breakout Weapon Case.
I'm using the following URL: http://backpack.tf/api/IGetMarketPrices/v1/?appid=730&format=json&key=myKey
It seems to be an issue with large numbers, because the Operation Breakout Case is the only one with a real Quantity of >2 million, while your api returns something around 2k
Hope you can fix this, thanks for support :)
