Kairos
One order book across every venue
Web · API
Kairos is a professional trading terminal for prediction markets that stacks the same contract from Kalshi, Polymarket, Predict.fun, and Hyperliquid into a single composite order book, then routes orders to the best price on any venue.
Data arrives in tens of milliseconds end to end, with colocated ingestion and streaming books instead of polling. Deploy algorithmic strategies from templates for market-making, arbitrage, and momentum trading — with built-in risk limits and backtesting against recorded books before going live.
Developers get REST and WebSocket APIs with aggregated cross-venue data, NBBO, scoped API keys, and a free sandbox. Draggable, resizable panels and saved layouts round out an interface built by a team from high-frequency trading firms and exchanges.
