Guild Wars 2

Not what they’ll buy an item from you but the price that they sell an item to you like say 10 spools of Gossamer thread?

Is it just 8 times the vendor price? Wiki seems to say that.

Alright, thanks! I think the items I’m most interested in (things like spools of thread) might be exceptions to that rule but I’ll check them out.

Thanks for continuing to develop new endpoints! The API is very convenient.

IFAIK, there are no API results for things sold from merchants.
maybe there will be one in the future, Lawton would know better than I :P
until then, I created my own. They are available here:
http://gw2profits.com/json/v3?disciplines=Merchant
I didn’t include all items, only those that were used in other recipes and are not temporary (unless they are only available during those temporary times. ex: candy corn cob). If you needed it, sorry I didn’t include which merchant it’s available from.
hope that helps!
