Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1/market-odds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time, crowd-sourced probability estimates for macro, crypto, political, or AI events and want Polymarket's live orderbook data rather than news sentiment or analyst forecasts. Prefer this over general news APIs when quantified market-implied probability and trading volume are needed.
Side effects
- No matching Polymarket market found for the given topic — returns empty or null results
- Topic keyword too broad or ambiguous, returning unrelated markets
- Payment failure via x402 protocol blocking the request
- Polymarket API downtime or rate limiting causing stale or unavailable data
- Topic references a resolved/closed market with no live orderbook
