Prediction Market Odds

Prediction market arbitrage in one call: keyword search across Polymarket AND Kalshi simultaneously -- no other market-data API aggregates both -- returning each match's live, real-money-backed outcome probabilities, volume, and close date, so you can spot pricing gaps between the two venues on the same event. Crowd-sourced forecasts for Fed decisions, elections, and macro events often beat polls and analyst surveys; pairs naturally with this API's own FOMC/economic calendar. Not ticker-specific. $0.03/call.
