How to make search using Splunk Rest API

I have following search query that I run on the Splunk search UI & It works fine: index=cpaws source=PFT buildNumber=14 type=REQUEST | stats p98(wholeduration) as currentRunP98Duration| appendcols [search index=cpaws source=PFT buildNumber=13 type=REQUEST | stats p98(wholeduration) as previousRunP98Duration1] | appendcols [search index=cpaws source=PFT buildNumber=12 type=REQUEST | stats p98(wholeduration) as previousRunP98Duration2] |eval avgP98=(previousRunP98Duration1+previousRunP98Duration2)/2 | eval success=if(currentRunP98Duration>=avgP98*0.1,"Good","BAD")| table success For printing out parameter "success", I was using the table command. Now I want to call the same query using the Splunk REST API and in return I want to get the success parameter value. How can I do that? I went through the Splunk REST API Documentation but I couldn't/didn't find anything helpful. Please help me.
