Please, make querying of CPC prices through AdWords API possible!

AdWords API allows querying of CPC keyword data, but it can't be queried with STFE 7.0.11.

Is it a kind of long and difficult way to make possible CPC querying through AdWords API?

That is a great suggestion and we will look at this for the next release. For future references, you can add suggestions here:
