Web api

Hi

I am storing some information in extra data field of the key. Is there a way I can get extra data along with keys with function call FindPKey? The problem is that I need to reiterate through all the keys with GetPKeyDetails to get extra data. With number of keys increasing this php call keeps slower and slower

Please, let me know if you have a solution.Thanks a lot.

Will it return me extra data along with other information ?
