Steam WebAPI - The Best Way to Find Steam Games and Items on the Market
If you own a Steam game or an item that you do not wish to sell on the market, there is a way to help you find the lowest prices for this item and others on the market.
This is a utility that will scan and search the market, as well as search databases of some of the largest marketplaces.
The best part is that all the data you see is in the public domain and is accessible via the Steam WebAPI.
The data is updated hourly, so you will not need to update it yourself. You can also access this data in bulk, by adding the URL directly to your phone or computer.
