Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events from Polymarket specifically, including orderbook depth and whale sentiment — not just headline odds. Prefer it over generic news or social sentiment APIs when you need market-implied probability expressed as a percentage with volume backing.
