Build an autobuyer for Sorare

I am looking for someone able to create an autobuyer for the Sorare site, base on an average price, would be able to buy a card as soon as it is put on the market place and that meets certain conditions such as : the price is X% lower than average price, age, position, rarity, min grade, floor price and max price.

Sorare is a fantasy Football game based on Ethereum Technology. API is in opensource available by GraphQL.
