About
Predictefy is a prediction-market data and trading infrastructure platform for developers, algorithmic traders, and research teams. Its REST API and SDKs provide a normalized way to retrieve market catalogs, prices, order books, trades, and historical data from supported venues. Users can stream live market updates over WebSockets, compare related markets across venues, and access market-matching and price-discrepancy data. The platform also documents order-building and execution workflows, portfolio and trader analytics, and tools for building automated strategies and AI-agent workflows, including an MCP server. Venue capabilities vary, and some analytics or data features depend on the subscription plan. Predictefy is designed for software teams and traders building research tools, trading bots, market monitors, and applications that use prediction-market data.
