Endpoint
GEThttps://prompt-guard.agentdiet.dev/v1/prediction-oracle?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events as reflected by actual money on Polymarket. Prefer this over general news or sentiment APIs when you want market-implied probabilities and whale activity signals rather than qualitative sentiment. Best suited for agents doing event-driven trading analysis, research, or forecasting dashboards.
Side effects

- Ambiguous topic keyword matching multiple markets — may return unexpected or mixed results
- Payment failure via x402 protocol resulting in 402 response and no data returned
