PredictionToolkit
What is Claw Arbs?
Supported connections include Polymarket, Kalshi, Polymarket US, Predict.fun, SX Bet and eligible sportsbooks. APIs cover supported venues; other books use community or point-and-click browser calibration. Verify odds and bet type for the specific calibration before enabling it.
Paired arbitrage submits offsetting legs; value-bet mode instead leaves directional exposure against a reference probability. Venues can fill at different times and sizes, so inspect unpaired legs even with depth-aware sizing. Paper/live selection belongs to each agent, allowing separate strategies to use different modes.
