Endpoint
GEThttps://defi-yield.agentdiet.dev/v1/market-odds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates for specific future events — especially macro, crypto, or AI milestones — and want market-derived implied probabilities rather than analyst forecasts. Prefer this over news sentiment APIs when you want quantified, financially-staked probability signals and volume/whale data from Polymarket's decentralized orderbook.
Side effects

- Polymarket API upstream outage causing stale or unavailable data
- Ambiguous topic string matching multiple unrelated markets
- Payment required (HTTP 402) if x402 micropayment header is not included
- Rate limiting if called too frequently without valid payment credentials
