申请入口那边写着，会员卡商户无需申请，可直接通过API接口，使用余额展示功能。请问会员卡商户是指哪些人？我已经开通了会员卡了算不算会员卡商户？余额展示功能是哪个API接口？？写的模模糊糊的，能否解释一下。

At the application entrance, it says that the merchant of membership card can use the balance display function directly through the API interface without applying. Who does membership card merchant refer to? I've opened a membership card. Is it a membership card merchant? Which API interface is the balance display function?? It's vague. Can you explain it.
