EDIT: Nevermind, i see now that scribe can craft this recipe at 0.
There seems to be a mistake either in the API or the wiki on the recipe for Vial of Linseed Oil (https://api.guildwars2.com/v2/recipes/10950). API reports min_rating of 0. Wiki says it's 400. Not sure if it's useful to report stuff like this, but i guess it doesn't hurt much.
