Endpoint
GEThttps://defi-yield.agentdiet.dev/v1/macro-odds?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's decentralized prediction market, especially for macro, crypto, political, or AI events where market-implied probabilities and whale sentiment are more actionable than news sentiment or analyst forecasts. Prefer this over general news APIs when you want quantified, monetarily-backed probability signals rather than qualitative coverage.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null result
- Polymarket API or orderbook data temporarily unavailable — may return stale or error response
- Ambiguous topic keyword matching multiple markets — may return multiple or lowest-relevance result
- Payment not processed (402) — endpoint requires $0.01 USDC per call via x402 protocol
