Endpoint
GEThttps://defi-yield.agentdiet.dev/v1/election-odds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probabilistic signals for macro, political, crypto, or AI events from Polymarket's decentralized prediction market. Prefer this over news sentiment APIs when you want market-implied probabilities with actual money at stake (rather than social sentiment), or when you need orderbook depth and whale positioning data. Best suited for AI agents that need to incorporate prediction market odds into trading, research, or decision-support workflows.
