How to parse data from an online game?

Question

Parsing

I want to write a program for market analytics in an mmo rpg game, it has an npc "dealer" who acts as a market. The goods in it are divided into categories and when a player puts something up for sale, the goods appear there. I need to get data from certain categories: the number of lots, the amount of goods in each lot, the cost of the lot. Is it possible to implement this without using computer vision?

Answer 1

If this is a desktop toy, then interact with memory only if without computer vision.
If this is a browser toy, then you need to dig into the page code, maybe there is data there.
