Gemini Trust Company Markets API

Public endpoints for browsing prediction markets. **Market Data:** Use these REST endpoints to discover active events and each contract's `instrumentSymbol` (e.g., `GEMI-FEDJAN26-DN25`). For active trading and market making, prefer [Prediction Markets WebSocket streams](/prediction-markets/websocket/streams) with that `instrumentSymbol`. - [List Events](/rest-api/prediction-markets/events/list-events) - Discover active events and instrument symbols - [Prediction Markets WebSocket Streams](/prediction-markets/websocket/streams) - Stream prices, depth, order events, and positions
