POST /amsin/alipay/business/credit/queryCreditQuota

Call this API to query the available loan quota.

Note:

To obtain and accumulate loan quota, you need to call the submitAttachment API to upload valid invoices.
Your loan quota will be subtracted once a credit grant expires or a loan is used.
You are recommended to call this API and query the current available quota before submitting additional invoices to apply for a credit grant.
To apply for additional credit grant, make sure it's no more than capLimitTotalAmount subtracted by grantTotalAmount and unpaidTotalAmount.
