# 查询账户余额和云手机余量

返回团队钱包余额与云手机使用额度。
- **前置条件**：调用成员需要费用权限。钱包按团队查询，因此这些数字是团队级的，不是成员级的。
- **副作用**：无。只读。可带退避安全重试。
- **单位**：`balance` 是钱包余额，单位为**分**，不是元。`remainingDuration` 是云手机剩余分钟数，`remainingConcurrency` 是并发槽位数；两者都会被截断到 0，不会为负。
- **返回内容**：只有这三个数字。上游存在冻结金额、已用与赠送时长的拆分、到期时间，但这里刻意不暴露。
- **说明**：钱包或额度查询任一失败，整个调用即失败；它从不返回部分数据。
