If you have read some of my other postings you know by now that I enjoy using the data from World of Warcraft in my projects. In my mind it’s a good amount of data that I can easily understand having played World of Warcraft for many years now. If you look at the Blizzard Community Platform API Documentation you will see that there is an Auction Resource that will return a link to a JSON file you can download that will show you all the auctions for a given server.
