Gemini Exchange API
Live market data from Gemini, the US-regulated crypto exchange founded by the Winklevoss twins, served straight from its public API — no key, nothing cached. The ticker endpoint returns a pair's snapshot — open, high, low and last price, best bid and ask, and the 24-hour percentage change — plus Gemini's distinctive hourly_changes array, the last 24 hourly prices, which lets you draw an intraday sparkline from a single call. The prices endpoint returns every Gemini pair in one call with its price and 24-hour change — the whole board at once. The orderbook endpoint returns the top of the order book with the spread. The trades endpoint returns the live trade tape, the most recent executed trades with price, amount, side and time. Everything is Gemini's live venue data from a regulated US exchange, nothing stored. This is the Gemini price, intraday-history and tape layer for any trading, charting or market-data app. Distinct from Coinbase, Bitstamp, OKX, Gate.io and Kraken venue APIs and from aggregated feeds — this is Gemini's own order book, tape and hourly price history. 4 endpoints, no key on our side, real-time.
