Welcome to the ISK-O-Meter (Stupid Animaniacs Reference)
Went down the route of developing a nano service, instead of a complex web of code doing 14 things at the same time, the bot checks price tags for whatever item you ask for on all major trade hubs. Figured I would make it public cos I am nice like that. Help yourselves. If you dont want to use it thats okay aswell 
Invite to server it doesent ask for a list of permissions either.
