## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction market orderbooks for macro, crypto, or AI events. It is ideal when you want implied market probabilities rather than analyst forecasts, and when whale sentiment or trading volume context is valuable. Prefer this over general news or sentiment APIs when you specifically want financialized crowd prediction data.

- Polymarket API unavailable or rate-limited — upstream fetch failure
