Endpoint
GEThttps://defi-yield.agentdiet.dev/v1/prediction-oracle?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events directly from Polymarket's decentralized prediction market. It is ideal when you want market-implied odds rather than model-generated forecasts, and especially useful when whale sentiment and orderbook depth are relevant signals. Prefer this over generic news or sentiment APIs when you need quantified probability rather than qualitative opinion.
Side effects
- No matching Polymarket market found for the given topic keyword

- Payment required (HTTP 402) if x402 micropayment header is missing or insufficient
- Topic string too vague to resolve to a specific market, returning multiple ambiguous results
