Auction prices of individual legendary item ranks

Greetings,
I couldn’t find a way to filter the auctions of specific Legendary item rank.
They all have same item id. How do we reach their rank info?
Thanks.

Hi,
look at the bonus-list from the item:
Bonus 6716 is 190
Bonus 6717 is 210
Bonus 6718 is 225
Bonus 6758 is 235

What does the bonus field mean and how do I use it to query the correct item?

did you ever find an answer for this? I’d like to find a way to determine what the bonus refers to.
