to speed up rendering.. i understand..
I must confess that i abused your smj2.herokuapp website to fetch information about cards available including mean and buyout price for my own table and logics, filters, sortings..
I am fetching all basics from the API now (CardID and i build the Card Names by my own, Auctions) and just fetch median once every week or two from your smj.cards.
My concerns are cleared so far!
And not to forget! smj.cards is a really nice masterpiece! Design, Graphs, Median, Reforge, CardID URL, and so on and on and on
