Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1/polymarket-feed?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events as reflected by actual money on Polymarket. Prefer this over news or sentiment APIs when you want market-implied probabilities backed by financial stake, not just opinion. Best for agents that need live prediction market data with volume and whale activity signals rather than static news headlines or social sentiment.
