Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events as reflected in actual prediction market trading activity, especially when whale sentiment and orderbook depth are relevant signals. It is best suited for agents that need to factor market-implied probabilities into decision-making, reporting, or monitoring workflows rather than relying solely on news sentiment or analyst forecasts.
