## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, AI, or geopolitical events from Polymarket's prediction market orderbooks. Prefer it over news sentiment or analyst forecasts when you want market-implied probabilities backed by real money and whale positioning signals. Ideal for agents performing event-driven research, trading signal enrichment, or probability-weighted decision making.
