Technical details
Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1/polymarket-live-odds-feed?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events sourced directly from Polymarket's live orderbook — especially when you want implied probability percentages and whale sentiment rather than news opinion. Prefer this over news APIs for quantified market consensus on binary event outcomes.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or error response
- Stale or unavailable orderbook data if Polymarket API is temporarily down
- Ambiguous topic matching multiple markets — may return aggregated or first-match results
- Payment failure via x402 if USDC balance is insufficient for the $0.01 per-call fee
