Endpoint
GEThttps://onchain-risk.agentdiet.dev/v1/prediction-markets?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events sourced directly from Polymarket's live orderbooks, especially when you want implied probability percentages and whale sentiment rather than just news sentiment or analyst forecasts. Prefer this over general news or sentiment APIs when you need market-backed probability data.
Side effects
- No matching prediction market found for the given topic keyword — returns empty or null results
- Ambiguous topic matches multiple markets — response may include multiple markets requiring disambiguation
- Stale or delayed orderbook data if Polymarket API is experiencing latency
- Payment failure via x402 protocol if USDC balance is insufficient
- Rate limiting if too many calls are made in rapid succession
