Subsequence markin/markout WS API

Hi,

I created three subsequences from a sequence with different mark-in and mark-out. The interplay API FindRelatives when called on the subsequences gives the list of referring masterclips. I do not get any specific timecode related information through which i can verify specific content of a subsequence, so my QC (quality checking) tool does a qc of the entire content.

Is there an Interplay WS API with which I can get to know only information related to the sub-sequence? 

Thanks!
