Check ability to borrow coin

Hi guys,
Question about endpoint https://www.binance.com/bapi/margin/v1/friendly/collateral/loans/retail/trial-calc-for-borrowing

In the Google Chrome:

  1. For guests all coins are always available for loan.
  2. For authorized users - message “there are currently insufficient loanable assets”.

How to use this API in Postman and get the same message? Or maybe we can check the ability to borrow coins in the other way? Thanks.

Un fortunately this API endpoint is not released, should not be used in client side.
