GSX (Global Service Exchange)
The Global Service Exchange (GSX) is Apple's internal, centralized database network used by authorized technicians to verify hardware integrity, warranty status, and legal ownership.
When you run a premium IMEI check, the tool taps directly into the GSX database to pull verifiable server-side proof of a device's history. This is the only reliable way to check the true Find My iPhone (FMI) status remotely, as Apple removed its public-facing checking tools to prevent malicious scraping.
