Choose this endpoint when you need real-time crowd-sourced probability estimates and orderbook-level sentiment for macro, crypto, political, or AI events from Polymarket specifically — particularly when implied probabilities, whale positioning, and live volume are needed rather than news sentiment or analyst forecasts.
Side effects

- Polymarket API unavailable or rate-limited — upstream data fetch fails
