Technical details
Endpoint
GEThttps://x402-audit.agentdiet.dev/v1/polymarket-alpha?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs real-time crowd-sourced probability estimates on macro, crypto, political, or AI events from Polymarket's liquid prediction markets. Prefer this over news or sentiment APIs when you need quantified implied probabilities rather than qualitative sentiment, and over generic crypto price feeds when the question is event-driven rather than spot-price-driven.
Side effects
- Topic keyword matches no active Polymarket market — returns empty or null results
- Ambiguous topic matches multiple markets — may return the wrong or most popular match
- Polymarket API or data feed unavailable — returns error or stale data
- Payment not processed (HTTP 402) — call fails before data is returned
- Rate limiting or quota exceeded at the upstream provider
