Can't find field

[Abdelkarim Bengrine]

Hello,  

Using the app I manage to easily find the field "Yearly lots sold" and "Sale price" in auctions results when I have selected an artist. But how can I retrieve those info using the api ? 

Also the api find the artist using an id, but let's say my user enter the name of the artist, is it possible to retrieve its info in another way ?

Thanks
