Is there an API to verify an item bind to account?
 

GetItemInfo retruns bindtype, but not inclued 'bind to account'

https://wow.gamepedia.com/API_GetItemInfo
https://wow.gamepedia.com/Enum_Item.ItemQuality
I would think the quality of 'heirloom' should represent that?

thanks for help
I've tried this method, it only works for real 'heirloom', like this https://www.wowhead.com/item=122356/...oulder?bonus=0
but some 'BOA' items have their own quality, like this https://www.wowhead.com/item=173416/...gloves?bonus=0
these kind 'BOA' items have their own quality, it's 'Rare'
so I wonder if there is a proper API for this

Scan the items tooltip

looks this is the only way to get it done, thanks for help
