we have a use case where we want to buy ETH or USDT using credit/debit card details i.e fiat, do binance apis support that as we are able to buy ETH directly from credit/debit card using UI but i am not sure about binance api if they also support it, i read create order api but it does not explicitly provide any details about it.

Unfortunately purchasing by fiat(credit card) is not support via API.
