What is PolyRouter?

A shared response format reduces the separate venue formats an application must handle. Listings retain platform and status filters and the market/event/series hierarchy. Books, historical trades, price series and supported public-user endpoints add detail after market discovery.

Sports endpoints give games a standardized identity using teams, date and league, alongside league, award and futures discovery. Keep the original venue and contract identity in any comparison: normalized data does not equalize settlement rules, and Manifold’s play-money markets are included beside real-money venues.

Our take on PolyRouter

The unified API and public tester make multi-platform exploration accessible. Beta access, shared request limits and mixed play-money and real-money markets still require deliberate application design.
