Endpoint
POSThttps://x402-audit.agentdiet.dev/v1/polymarket-feed?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, crowd-sourced probability estimates and orderbook sentiment from Polymarket specifically — especially for crypto, macro, political, or AI events where prediction market implied odds are more useful than news headlines or analyst forecasts. Prefer this over generic news or sentiment APIs when you need a quantified probability (e.g. 73% Yes) rather than qualitative sentiment.
Side effects
- Topic keyword too vague — no matching Polymarket market found
- Market not yet listed on Polymarket for the requested event
- Payment failure via x402 protocol — call not executed
- Network latency causing stale or unavailable orderbook data
- Ambiguous topic string matching multiple unrelated markets
