I know two methods (correct me if I am wrong) for getting the defindex of a CS:GO item: 1. It is actually not available anymore but back in the days (before March 2017) you could get someone's invetory list and one of the item attributes was defindex. 2. You can use inspectItem function from node-globaloffensive to get info about an item and one of the attributes is defindex. (side question here: could you confirm that you need CS:GO on your account to use this?) So my question is: are there other ways for acquiring this information?
