PolyRouter
Unified API providing real-time and historical data from multiple prediction market platforms through a single interface.
Overview
PolyRouter is a unified API designed to simplify access to prediction market data by aggregating multiple platforms into a single, standardized interface. It connects to seven major prediction market platforms including Polymarket, Kalshi, Manifold Markets, Limitless, ProphetX, Novig, and SX.bet. Developers can retrieve real-time market data, historical price information, and sports betting odds through consistent JSON or CSV formats, eliminating the need to integrate multiple disparate APIs. This streamlines development workflows and accelerates building prediction market applications or analytics tools.
The API supports specialized endpoints for sports betting markets, covering major leagues such as the NFL, NBA, MLB, and NHL, with standardized game and league identifiers. PolyRouter also offers a Market Connector Protocol (MCP) server that enables integration of real-time prediction market data into AI workflows and assistants like Claude Code. The platform is built by experienced prediction market infrastructure developers, ensuring reliability and domain expertise.
PolyRouter is accessible via a RESTful API with sub-second response times and generous free tier limits, requiring only a simple sign-up to obtain an API key. Comprehensive, interactive documentation and client libraries facilitate quick onboarding. Its unified approach reduces integration complexity and supports advanced filtering and cross-platform analysis, making it suitable for analytics teams, DeFi projects leveraging prediction data, and financial institutions interested in market sentiment and event probabilities.
