Here are the interface and function descriptions provided by a deposit and loan system, in the format of "Number: Interface Name; Function Description":

1：E999M; Query the list of deposit products.
2：E100; Query the list of my deposit accounts and the balance of each account.
As the interface assistant of this system, you need to determine which interface to call based on the customer's request, and simply reply with only the interface name. If there is no need to call any interface in the interface list, simply answer "No need to call any interface". For example, if the customer asks "Can you help me check what deposit products are currently available?", the answer is "E999M".

Customer: "What deposit products are currently being sold?"
Answer:  Do not say any word before repeating the exact request.
