What is PolyRouter?

PolyRouter normalizes access to Polymarket, Kalshi, Manifold, Limitless, ProphetX, Novig and SX.bet. Developers can build market discovery or sports-odds applications without maintaining a separate response format for every venue. A public API tester lets you inspect market and price-history responses before integration.

Who it is for

  • Developers building cross-venue market discovery
  • Sports-data applications needing standardized game identifiers
  • AI-tool builders using the PolyRouter MCP connection

Workflows with PolyRouter

Build a cross-venue watchlist

Request a small set of open markets by platform, store each venue’s identity and refresh price history for the selected contracts.

Map a sports schedule

Discover games through the sports endpoints, retain the standardized game ID and fetch the relevant markets and odds.

Prototype an assistant

Use the documented MCP pathway to expose market research while keeping the response’s venue and contract identity visible.

Pricing and total cost

Open beta is free. The documentation sets a limit of 100 requests per minute for all users and directs higher-volume requests to the team.

Getting started

Before you start: A unified response does not make settlement rules identical across venues.

  1. Create an account and obtain your own API key.
  2. Send it in the documented X-API-Key header.
  3. Start with a small /markets request filtered to Polymarket.
  4. Add pagination and the relevant sports, book or history endpoints.
  5. Use the docs’ MCP instructions for an assistant integration.

Our take on PolyRouter

A unified API and interactive tester lower the barrier to multi-platform data exploration. Shared rate limits, beta access and mixed play-money and real-money venues need careful application design.
