Usage cost will be $0.03 per one thousand ad impressions. In this case, you are under no obligation to sell your inventory via Rontar.RTB, but can do so if you want.

It is important to note that only real ad impressions will be charged. All empty requests to the system are completely free of charge, which is not always true of similar ad server solutions.
