Proposal to create "IoT SIM Fraud Prevention" API:
This API allows enterprise customers to query risk control information related to IoT SIM cards, such as machine-card binding, region restriction. With this information, enterprises can assess the security and reliability of IoT cards, helping to assess security, detect, and prevent possible fraud.

This API allows enterprise customers to subscribe to risk control information related to IoT SIM cards. When the device or region bound to the IoT card changes, the customer can be notified in a timely manner through the callback address registered by the customer, making it convenient for the customer to identify endpoint risks in a timely manner.
