Vendor Item Listing Prices
Different vendors can sell an item at different prices, and some of those vendors are not player accessible, so its difficult to include this in the item endpoint. There were a few requests for a list of all vendors, here is the github issue for it: https://github.com/arenanet/api-cdi/issues/235
I’ve actually wobbled a bit on my “IT’S IMPOSSIBLE” opinion and think there might be a way to expose vendor data but it’s still kind of a mess.
I know it’s not quite the same, but I’ve built a lot of my own recipes, some are items purchased from vendors:

I should point out: a lot of the ‘ingredients’ (cost to buy merchant’s items) are negative numbers. those correspond with their currency ID from the currency API (-1 = coin, -2 = karma, -3 = laurel, etc.)
I didn’t do every merchant, only permanent ones, or items that are required for another recipe. If there are any you know of that I missed, let me know (it’s on my things to do to add the ones in bloodstone fen)
