Overview
Finage is a financial data provider offering real-time and historical data for stocks, forex currencies, cryptocurrencies, indices, and ETFs through a single API. You can get stock prices, currency exchange rates, and crypto quotes with one API key, making it convenient for building multi-asset financial dashboards. It offers a free tier that is suitable for learning and small projects.
Beginner Tip
Start with the /last/stock endpoint to get the current price of a single ticker — it is the simplest call and a great way to verify your API key is working. Use WebSocket connections instead of polling for real-time price updates to stay within rate limits.
