coin-ticker is a Node.js library that provides a unified interface for fetching real-time cryptocurrency market data from multiple exchanges like Bitfinex, Coinbase, and Kraken. It simplifies the process of integrating Bitcoin, Ethereum, Litecoin, and other asset prices into applications by returning consistent ticker data (last price, ask, bid, volume, etc.) in a single format. This project is ideal for developers building crypto-related apps who need reliable and easy access to exchange data without dealing with individual API integrations.
