The MobileIron agents through 2021-03-22 for Android and iOS contain a hardcoded API key, used to communicate with the MobileIron SaaS discovery API, as demonstrated by Mobile@Work (aka com.mobileiron). The key is in com/mobileiron/registration/RegisterActivity.java and can be used for api/v1/gateway/customers/servers requests.
