## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events sourced directly from Polymarket's prediction market orderbooks. Prefer this over general news or sentiment APIs when you want quantified implied probabilities backed by real financial stakes and whale-level orderflow signals.

## Known failure modes
