What Is a Cryptocurrency API?
A cryptocurrency API (Application Programming Interface) is a set of protocols and tools that allow developers to interact with blockchain networks, exchanges, and financial platforms. These APIs enable applications to fetch real-time market data, execute trades, manage wallets, and integrate blockchain functionality without building infrastructure from scratch. By acting as a bridge between software systems, cryptocurrency APIs simplify complex processes like transaction verification and data analysis.
