You can check your device integrity against Googles SafetyNet Attestation API.

If you want to check on a regular basis you are able to unlock unlimited checks via one time in app purchase.

Following parameters are tested:

• Hostname is attest.android.com
• Generated UUIDs of request and response are matching
• Package name of app is identical
• Response was received within given time
• APK certificates are matching
• Device profile is valid (CTS Profil)
• Integrity is given (BasicIntegrity)

In addition the apps shows you the advices from Google if check failed.

I also offer SafetyNet implementations with backend for you or your company.
