Endpoint
GEThttps://x402broker.com/v1/event-probabilities?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates from an active prediction market rather than sentiment scores, analyst forecasts, or news summaries. It is ideal when you want market-implied odds with volume and whale positioning context for macro, political, crypto, or AI events specifically listed on Polymarket.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null results
- Topic too vague or ambiguous to resolve to a specific market — may return multiple unrelated markets
- Polymarket API unavailable or rate-limited — upstream data fetch failure
- Payment not processed (x402 flow failure) — endpoint returns 402 without data
- Stale or low-liquidity market returned if the event has low trading activity
