Endpoint
GEThttps://preflight.agentdiet.dev/v1/prediction-oracle?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-implied probabilities for a specific event (crypto, macro, AI, political) sourced directly from Polymarket's live orderbook, especially when you need whale sentiment or volume alongside the odds. Prefer this over static news or sentiment analysis tools when you want market-priced probability estimates reflecting actual money at risk.
Side effects

- Stale data if Polymarket API is temporarily unavailable
- Ambiguous topic string matches multiple markets — response may return multiple or unexpected markets
- Payment failure via x402 protocol if USDC balance is insufficient
- Rate limiting or timeout if Polymarket upstream is slow
