Technical details
Endpoint
GEThttps://workflows.agentdiet.dev/v1/prediction-oracle?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates from Polymarket for macro, crypto, political, or AI events — especially when you want both implied probabilities and whale sentiment in one call. Prefer this over general news or sentiment APIs when you specifically need prediction market consensus odds backed by on-chain trading volume.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null market data
- Polymarket API or upstream data feed is temporarily unavailable — returns service error
- Ambiguous topic matches multiple markets — may return the most relevant or require refinement
- Payment of $0.01 USDC via x402 fails — request is rejected with 402 Payment Required
