Include TCGPlayer API ProductID in card info.
Integrate the TCGPlayer API to have TCGProductID as a field on each card. Category ID is always 1 for Magic Each MTG set would have a group in category 1. For example Battlebond is group 2245 Each card then has a productid. For example Spire Garden is id 166659 Card data also contains an image link. https://6d4be195623157e28848-7697ece4918e0a73861de0eb37d08968.ssl.cf1.rackcdn.com/166659_200w.jpg
Inclusion of this data would allow developers using MTGJson to get TCG prices and link more easily.
This would be a good extension as soon as that system is in place. I'll see if I can write up a detailed proposal soon, hopefully next week.
I’d be in for a 4.1 to include this for sure
