Endpoint
GEThttps://preflight.agentdiet.dev/v1/fomc-rate-odds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events from Polymarket's decentralized prediction markets, especially when you want orderbook depth and whale sentiment in addition to raw odds. Prefer this over news APIs or sentiment tools when you want market-implied probabilities rather than qualitative opinion.
