Get id of the item from where a certain recipe is learned

Is there a way to get the id of the item from which a certain recipe is learned?. since the endpoint /data/wow/recipe/{recipeId}; send name, id, media and materials nothing else. This list of recipes is obtained from the endpoint /data/wow /profession/{professionId}/skill-tier/{skillTierId} but I don’t see a way to get to the item, teacher or way to learn it :confused:
