Bot sorare (Max budget 100€)

Sorare is a Fantasy Football game released in 2019 where you collect digital cards (NFT) bearing the image of football players.- sorare.com
The game is based on Ethereum technology in which its own marketplace is integrated. The API is in Opensource made available by GraphQL.
Objectives: – Create an Autobuyer bot which, based on a given average price, would be able to buy a card as soon as it is put on the market. Provided that it is X% lower than its average price, it is a question here of spotting a price error and buying it as quickly as possible, before the other bots in service on the platform.
In this platform there is 4 differents kind of cards so I would like to put the bot wherever and choose in which one I want
Also there are differents leagues I would like to choose in which one I’ll bid
For Example: -If the newPlayer on the market is 10-20-30% cheaper then the average price, fast automated buy. – After that more attributes: Only Players from 18-35 years old or only from European Leagues. etc. – Some sort of protect from not getting banned if its possible.
