Endpoint
GEThttps://alpha-stream.agentdiet.dev/v1/polymarket-feed?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction market for macro, crypto, AI, or political events — especially when you want implied market odds (not just news sentiment) and whale-weighted trading volume as a signal of conviction. Prefer this over general news or sentiment APIs when quantitative probability data is required.
