I'm not sure if it works with the Google API's but usually e.g. with the GitHub API you can send the ETag in your GET request header and if nothing changed (304) it does not count to the quota. It wouldn't solve all the problems but could at least help to stay inside the quota.

I am already doing that, because of that only I am able to survive 2000 users. I want to expand and publicize my app and give users an excellent experience.
