Endpoint
GEThttps://hn-pulse.agentdiet.dev/v1/event-probabilities?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-wisdom probability estimates for macro, crypto, political, or AI events as reflected in actual prediction market trading activity on Polymarket. Prefer this over news sentiment tools when you want market-implied probabilities backed by real money and whale order flow rather than opinion or headlines.
