PolyGram API documentation
Build on top of PolyGram with our REST API and real-time WebSocket streams — market data, trading, portfolio management, and white-label integration.
The PolyGram API gives developers programmatic access to every prediction market on the platform. Fetch live odds, historical prices, order book depth, and trade volume through simple REST endpoints authenticated with API keys. For real-time updates, connect to our Server-Sent Events stream and receive price ticks, order fills, and resolution events the moment they happen — no polling required. The trading API supports market orders, limit orders with time-in-force options (GTC, IOC, FOK), and advanced conditional orders including stop-loss, take-profit, and trailing stops. All responses are JSON, rate-limited at generous thresholds, and documented with OpenAPI schemas. White-label partners can use the same endpoints to power their own branded prediction market front-ends, with full custody handled by PolyGram's wallet infrastructure.
