...payments only in Tether (USDT) BEP-20, similar to what is done at PixSwap (). I would like to allow my customers to buy USDT directly from me, using the PancakeSwap API for token purchases and the EFi API (formerly Gerencianet) to process payments via PIX. The API documentation can be found at Additionally, I plan on charging a fee on each transaction. The workflow would look something like this: The user inputs the amount of USDT they wish to purchase and the wallet address where they want the tokens to be sent. The system uses the EFi API to process the payment via PIX. Once the payment is confirmed, the system uses the PancakeSwap API to purchase the requested amount of USDT. The system then sends the USDT tokens
