PolyRouter is a unified prediction market API aggregator that provides software developers, AI builders, and sports analysts with a single REST API to instantly access real-time data across platforms like Polymarket, Kalshi, Limitless, and Manifold.
About PolyRouter
What is PolyRouter?
PolyRouter is a unified prediction market API aggregator. It serves as a central hub that gathers data from many different prediction platforms and organizes it into one standard format.
Instead of building separate connections to collect data from networks like Polymarket, Kalshi, Limitless, and Manifold, you use our single interface. By combining real-time market data and price history into one simple place, PolyRouter allows you to access massive amounts of prediction market information with just a single REST API request.
Who is it for?
This platform is built specifically for software developers, data scientists, and researchers who need reliable prediction market data without the struggle of juggling multiple platform integrations. If you want to focus entirely on building your application instead of maintaining API connections, this tool is for you.
- AI Builders: Using the specialized PolyRouter MCP server, developers can supply live market data directly to artificial intelligence workflows and agents like Claude Code.
- Sports Analysts: Individuals tracking sports betting markets can utilize our custom sports endpoints. This makes it easy to collect data on upcoming games, league futures, and player awards across major leagues like the NFL, NBA, MLB, and NHL.
- Market Researchers: Users performing cross-platform analysis can instantly compare outcomes and statistics across different prediction websites at the same time.
How it works?
The system operates through a very straightforward technical process. You start by receiving an API key from our platform. With this key, your application makes a standard request to our unified REST API.
When you send that one single command, PolyRouter's backend instantly contacts all the supported prediction markets for you. It pulls the raw information, translates all the different website structures into one clean and unified data format, and returns the simplified results directly to your code.
Because the open beta is currently live, you can even explore how the platform functions before writing any software. We provide an interactive API tester that lets you pull real market data and check price history live, with no API key required.
