Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/fomc-rate-odds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-implied probabilities and whale activity for macro, crypto, or AI events from Polymarket specifically — as opposed to general news sentiment or historical price data. Prefer this over generic search endpoints when the user explicitly wants prediction market odds, implied probabilities, or market-based event forecasts rather than analyst opinions or news articles.
