Endpoint
GEThttps://workflows.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, political, or AI events as reflected in actual money markets rather than polls or analyst forecasts. It is especially useful when whale sentiment and orderbook depth are needed alongside implied probabilities, and when the question maps naturally to a Polymarket prediction market. Prefer this over general news APIs when you need quantified probability rather than narrative, and over static data sources when you need live, continuously updated market consensus.
Side effects
- Topic keyword too vague returns no matching market or empty results
- Polymarket market not found for niche or obscure event topics
- Payment failure via x402 protocol results in 402 response blocking data access
- Rate limiting or upstream Polymarket API downtime causes delayed or unavailable data
- Ambiguous topic matches multiple markets, returning mixed or aggregated results
