Endpoint
GEThttps://prompt-guard.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 sourced directly from Polymarket's active orderbooks. It is preferable over news sentiment APIs when you want financially-backed implied probabilities rather than qualitative sentiment, and over static data sources when you need live, up-to-the-minute market odds and whale positioning data.
Side effects
- No matching Polymarket market found for the given topic keyword — may return empty or low-confidence results
- Topic too vague or ambiguous leading to mismatched market selection
- Polymarket API upstream unavailability causing stale or missing data
- Payment failure via x402 resulting in 402 response without data
- Rate limiting if called at high frequency
