Gemini

About Gemini

Gemini's REST API provides programmatic access to its cryptocurrency exchange, covering order management, market data, derivatives, and fund management. Endpoints are organized by category, including order creation and cancellation, real-time and historical market data (symbols, order books, ticker prices, trading volume), perpetual contract trading, margin trading with leverage and account health monitoring, and bilateral clearing workflows including broker-facilitated clearing.

The API also covers prediction markets, with REST endpoints for browsing event-based contracts, retrieving event details, accepting terms, and querying open and historical positions after restarts or missed messages; live prediction market trading and quote/cancel flows are handled over WebSocket rather than REST. Additional endpoints support fund management (deposits, withdrawals, internal transfers, linked payment methods), OAuth 2.0 for authorizing third-party access to Gemini accounts, and administrative functions for subaccounts, API keys, and account-level settings.

This API is intended for developers building applications that interact with Gemini's trading, derivatives, margin, clearing, or prediction market systems, or that need to manage account and fund operations programmatically.
