Grantiva verifies devices using Apple’s App Attest API, issues JWT tokens with device intelligence, and provides risk scoring. No client-side API keys needed — your app is identified automatically by Bundle ID and Team ID.

​
How it works

  1. Your app requests a challenge from the Grantiva server
  2. App Attest creates an attestation on the device using Apple’s framework
  3. Grantiva validates the attestation and scores the device
  4. A signed JWT token is returned with device intelligence and custom claims
  5. Your backend verifies the token to make trust decisions
No API keys are sent from the client. The server identifies your app by its Bundle ID and Team ID, which are sent automatically by the SDK.

​
Pricing

Flat monthly pricing. No per-attestation fees or overages.
