GEThttps://prompt-guard.agentdiet.dev/v1/polymarket-prediction-stream?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-wisdom probability estimates for macro, crypto, political, or AI events sourced directly from Polymarket's live orderbooks. Prefer it over static news sentiment or analyst forecasts when you want market-implied probabilities backed by actual money. Especially useful when tracking rapidly evolving events where consensus shifts quickly, or when you want to detect whale positioning as a leading signal.
