Choose this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction markets for macro, crypto, or AI events, especially when you want implied Yes/No odds, orderbook depth, volume, and whale positioning in a single structured response. Prefer this over static news sentiment or analyst forecasts when you want market-priced probabilities backed by real money.
