API ticker only BTC or USDT pairs

Hello. 1500+ transaction pair data comes when pulling prices through the API. But this slows down the system and processes. For example, is it possible to bring prices that are only USDT?

You can use /api/v3/exchangeInfo endpoint to get all tradable coin pairs and filter it accordingly to your preference. Then you can query the ticker endpoint with the filtered symbols you got. The ticker endpoint does not support any filtering at the moment.
