## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates and market-implied odds for macro, crypto, or AI events from Polymarket, especially when whale sentiment and orderbook depth are needed alongside raw probabilities. Prefer this over news sentiment or social media analysis when you want financially-backed, skin-in-the-game probability signals rather than editorial opinion.
