Endpoint
GEThttps://onchain-risk.agentdiet.dev/v1/polymarket-live-odds-feed?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need live, on-chain prediction market consensus odds for macro, crypto, or AI events directly from Polymarket's orderbook, including volume and whale sentiment — rather than polling social media or news sentiment, which lack probabilistic pricing. Prefer this over generic news APIs when you need a quantified probability estimate backed by real money.
Side effects
- No matching market found for the given topic keyword — returns empty or null result
- Polymarket API rate limit or downtime causing stale or unavailable data
- Ambiguous topic string matching multiple unrelated markets
- Payment required (HTTP 402) if x402 credit is not provisioned
- Very low-liquidity markets may have unreliable implied probabilities
