Endpoint
GEThttps://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, geopolitical, or AI-related events from Polymarket's decentralized prediction market. Prefer this over news sentiment APIs when you want market-priced probabilities and volume signals rather than qualitative sentiment, and over static forecast models when you need live, continuously updated odds reflecting current whale and retail trader positioning.
Side effects
- No matching Polymarket market found for the given topic — returns empty or null results
- Ambiguous topic keyword matches multiple markets — may return unexpected market
- Stale or delayed data if Polymarket API is temporarily unavailable
- Rate limit or payment failure via x402 protocol causing 402 response
- Highly niche topics with low liquidity may return minimal orderbook data
