Endpoint
GEThttps://onchain-risk.agentdiet.dev/v1/macro-odds?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, crowd-sourced implied probabilities from Polymarket for macro, crypto, or AI events — especially when you want orderbook depth, volume context, and whale sentiment rather than just a headline probability. Prefer this over general news or sentiment APIs when you want market-priced belief, not editorial opinion.
Side effects
- No matching Polymarket market found for the given topic — returns empty or null results
- Ambiguous topic keyword matches multiple markets — may return multiple or incorrect markets
- Polymarket API unavailable or rate-limited — endpoint may return 503 or timeout
- Payment not completed via x402 — returns HTTP 402 Payment Required
- Stale or low-liquidity market — orderbook may show wide spreads and low volume with unreliable probabilities
