## When to prefer this

Use this endpoint when you need real-time crowd-sourced implied probabilities and whale sentiment for macro, crypto, or AI events from Polymarket specifically — ideal for agents that need to incorporate prediction market signals into trading, research, or news analysis workflows. Prefer this over general news or sentiment APIs when you want market-priced probability estimates rather than qualitative opinions.
