Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events, particularly when you want market-implied odds rather than analyst forecasts. It is ideal for agents that need to ground decisions or reports in live prediction market data from Polymarket, including volume and large-trader (whale) sentiment signals.
