An Exchange API (Application Programming Interface) allows developers to connect software applications to a cryptocurrency exchange. Through this interface, users can programmatically access exchange functionalities, such as retrieving market data, executing trades, or managing their accounts.APIs typically offer various endpoints that users can interact with, including options for checking current prices, historical trade data, and order books. This accessibility enables traders to create automated trading bots or integrate trading functions into their own applications.Security is vital for APIs since they handle sensitive operations. Most exchanges require API keys and may implement additional layers of authentication to ensure secure access.In summary, an Exchange API is a powerful tool for accessing and managing trading operations on cryptocurrency exchanges, facilitating automation and integration into wider financial tools or platforms.
