The Verizon ThingSpace Device Location API provides a way to find the location of IoT devices in an account. This includes features such as; verify fixed assets, track mobile assets, plan efficient truck routes between devices, estimate the arrival time of a delivery and more. The Device Messaging API is used with all Open Development certified IoT devices like; routers, modems, vending machines with embedded modules, etc. to request a device's current location, or request the previous location from the cache. It allows you to compare the current and cached locations to verify that a device has not moved, or to see how far it has moved.
