Endpoint
GEThttps://serp-extract.agentdiet.dev/v1/prediction-markets?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates from Polymarket for macro, crypto, AI, or political events — especially when you want implied odds, orderbook depth, and whale sentiment in a single call. Prefer this over general news or search endpoints when you specifically need market-implied probabilities rather than editorial opinion or historical data.
