## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events from Polymarket's prediction market, especially when you want orderbook-derived Yes/No implied odds, volume context, and whale sentiment in a single call. Prefer this over general news or sentiment APIs when you need a quantified market-consensus probability rather than qualitative opinion.

- Polymarket API unavailable or rate-limited — upstream data fetch fails
- Market exists but has very low liquidity — probabilities may be unreliable
