Owning Tarkov’s Marketplace

Flea Market Botting

Escape From Tarkov is a first-person shooter in its alpha stage of development. It has an in-game economy with unique characteristics that help drive a very stable in-game marketplace. The marketplace allows players to buy and sell items they find while in game. Item prices each have a stable supply and demand which drives the market price to a stable price point. Some players list below market rate in order to sell their items as quickly as possible. This provided me with an opportunity, can I write software that will detect these listings and buy them up before anyone else? If so, I can turn a constant profit off the market place, providing a seemingly endless supply of cash. So that is what I did.

To provide some more context, Tarkov uses a REST api for all marketplace and trading requests. Actually, a majority of the games requests, excluding those from gameplay, are done over this API. The one thing is this API requires an active session to be established prior to any requests being processed. When you log in through the launcher, this session is created and is subsequently passed off to the game application when you click play. Initially, the API was on the HTTP protocol, so as long as I had the session, I could send the request from just about anywhere. With the later updates, this was moved to TLS v1.0 and TLS v1.2, HTTPS. HTTPS forced me to take a different route, but that will come up down the line.

With that intro out of the way, let’s own the market.
