Gemini API
Overview
Gemini is a U.S.-regulated cryptocurrency exchange API that provides public market data without authentication, making it beginner-friendly. It returns current bid/ask prices, recent trade history, and order book snapshots for major crypto pairs like BTC/USD and ETH/USD. Because no API key is needed for read-only market data, you can start querying immediately.
Beginner Tip
No sign-up is required to fetch public market data from Gemini; simply call the REST endpoint directly to get current BTC/USD prices in seconds.
