Mantis is a cross-venue prediction market router. One query searches Polymarket, Kalshi, Limitless, Myriad, SX Bet and PredictIt and returns the best price, best liquidity, and any cross-venue arbitrage spread. Tools: route_market, get_arbitrage, execute_url, get_quote, get_unmet_demand. Free self-serve API key; paid tiers add higher limits and webhooks. No account needed to search.
