Endpoint
GEThttps://preflight.agentdiet.dev/v1/polymarket-odds?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction market for macro, crypto, political, or AI events. It is ideal for agents that need market-implied odds rather than model-based forecasts, or that want to gauge speculative sentiment and whale positioning on a specific event outcome. Prefer this over generic news or sentiment APIs when you need a quantified probability with associated trading volume as a confidence signal.
