# Routeur API

> Proven relations between Kalshi and Polymarket markets, and the history and signals built on them.

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.

  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](/data-and-limits).
