Routeur reads every open market on Kalshi and global Polymarket and proves which ones imply, exclude or equal each other, using each venue’s structured contract terms and exact arithmetic. Nothing is inferred from a market’s wording, and conflicting evidence is withheld rather than guessed. On top of that graph the API serves live prices across both venues, recorded quotes and trades, mispricing leads sized against real order books, unusual-flow signals, and strategies measured against settled history.

Moves, large fills, one-sided money and unusual flow.

Discovery

Search in plain language and browse by topic.

Research

How prices in each band actually resolved.

Strategies

Rules history paid for, and what fits them today.
The API is in private preview. Keys are issued by the Routeur team; responses are observations of public venue data, not quotes or investment advice. See Data and limitations.
