Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events from Polymarket's prediction market. Prefer this over traditional news or sentiment APIs when you want market-implied probabilities backed by real money, orderbook depth, and whale positioning data rather than sentiment scores or analyst forecasts.
