Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events as priced by actual prediction market participants on Polymarket, especially when you want orderbook depth, whale sentiment, and volume alongside implied probabilities. Prefer this over news sentiment or analyst forecasts when you need a market-clearing probability that reflects financial skin-in-the-game.
