An anti-abuse API called SafetyNet Attestation enables app developers to evaluate the Android device that their app is currently operating on. If you want to check whether your servers are communicating with your legitimate app that is running on a legitimate Android device, you should utilize the API as part of your abuse detection system.

An Android app called YASNAC (short for Yet Another SafetyNet Attestation Checker) illustrates the SafetyNet Attestation API. The 10,000 requests per day cap on the YASNAC API key. You will receive a warning if the quota is used up and won't be able to use it again until the following day when it is replenished.
