Endpoint
GEThttps://onchain-risk.agentdiet.dev/v1/event-probabilities?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-implied probabilities for macro, crypto, political, or AI events from Polymarket's decentralized prediction market — particularly when you want live orderbook-derived odds rather than static forecasts or analyst estimates. Prefer this over news APIs when the goal is market consensus probability rather than narrative coverage.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null result
- Polymarket API unavailable or rate-limited — upstream fetch failure
- Ambiguous topic matches multiple markets — result may include multiple market entries requiring disambiguation
- Payment not processed (x402 flow failure) — endpoint returns 402 without data
- Very low-volume markets may have unreliable or stale orderbook data
