Endpoint
GEThttps://defi-yield.agentdiet.dev/v1/prediction-markets?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time, crowd-sourced probability estimates for specific macro, crypto, political, or AI events from Polymarket's live orderbook — especially when you want implied market odds rather than model-based forecasts. Prefer this over general news or sentiment APIs when you need quantified probability with volume and whale activity context.
Side effects

- Polymarket API upstream outage causing stale or unavailable data
- Ambiguous topic string matching multiple unrelated markets — may return unexpected market
- Payment failure via x402 protocol resulting in 402 response and no data returned
