Endpoint
GEThttps://domain-osint.agentdiet.dev/v1/market-odds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events as priced by actual market participants on Polymarket. Prefer this over general news or sentiment APIs when you want quantified probability (e.g. 67% Yes) rather than qualitative sentiment, and when whale orderflow or volume context matters for decision-making.
Side effects

- Rate limiting or payment failure (HTTP 402) if payment credentials are invalid
