Binance API provides a variety of free services. Its public API allows users to access market data, such as price and trading volume, without any cost. However, utilizing additional features like trading, account information, and withdrawals may require verification and potentially incurring fees based on usage or specific services. Binance also offers a premium API service, which offers advanced functionality for professional traders at a cost. While basic functionalities of the Binance API are free to use, users should carefully review the terms and conditions to understand any potential charges associated with advanced features.
