Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, geopolitical, or AI events backed by actual money at stake on Polymarket. Prefer this over news sentiment or analyst forecasts when you want market-implied probabilities with volume signals and whale activity. Best suited for agents doing event-driven research, risk assessment, or trading intelligence where prediction market consensus is more actionable than opinion-based sources.
