Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events — specifically pulling live Polymarket orderbook data including implied odds and whale sentiment. Prefer this over news APIs when you want market-consensus probability rather than raw news, and over static data sources when you need live, continuously updated prediction market odds.
