Technical details
Endpoint
POSThttps://defi-yield.agentdiet.dev/v1/event-probabilities?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, geopolitical, or AI-related events sourced directly from Polymarket's live orderbooks. It is especially useful when you want market-implied probabilities (rather than model-based forecasts) and whale sentiment as a signal. Prefer this over general news or sentiment APIs when the question has a binary Yes/No resolution and you want financially-backed consensus odds.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null results
- Polymarket API downtime or rate limiting causes delayed or failed data fetch
- Ambiguous topic keyword matches multiple unrelated markets, returning mixed or irrelevant results
- Payment failure via x402 protocol prevents endpoint access
- Stale data returned if Polymarket orderbook has low liquidity or no recent trades
