POSThttps://onchain-risk.agentdiet.dev/v1/polymarket-odds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events sourced from Polymarket's decentralized prediction market. Prefer this over general news or sentiment APIs when you want a quantified, market-based implied probability backed by real money. It is especially useful for agents doing risk assessment, scenario planning, or trading strategy that requires live prediction market intelligence.
Side effects
- No matching Polymarket market found for the given topic keyword — returns empty or null result
- Polymarket API unavailable or rate-limited — upstream timeout or 5xx error
- Ambiguous topic matches multiple markets — may return the most relevant or all matches
- Payment not processed (x402 flow failure) — endpoint returns 402 with payment details
- Stale data if Polymarket orderbook has low liquidity or the market has resolved
