How to display statistics from Yandex.Direct using the API on your website?

Question

API

With the metric, I figured out how to display the expense for the last day and how many target visitors. But I’ve been fiddling with API Direct all day and can’t figure out how to display the cost for the past day, the average click and the number of clicks of companies in total.
With the metric did so, but with Direct in any way.
As a result, I get the code
----
{"data":[{"ClicksSearch":203,"SumSearch":376.53,"SessionDepthSearch":"3.03","SessionDepthContext":null,"ClicksContext":0,"GoalCostContext" :null,"GoalCostSearch":"2.67","GoalConversionSearch":"74.60","SumContext":0,"GoalConversionContext":null,"StatDate":"2015-08-11","ShowsSearch":1109," CampaignID":8543753,"
