Content based report

I’m trying to show the impression and interaction of specific content on my website using the reporting API. I have 4 contents created and want to get the impression and interaction of each one something like passing the content name as an attribute.

http:/example.com/analytics/?module=API&method=Contents.getContentNames&idSite=1&segment=contentName==AD4&period=day&date=last2&format=JSON&token_auth=annonymus

i have tried this but its getting all contents report. i need report of only content named AD4
