Endpoint
GEThttps://joe-market-data.marnick-yezo.workers.dev/pm-searchWhen to prefer
Use this endpoint when you need to find Polymarket prediction market odds on any current event, macro trend, or crypto outcome. It is the right choice when users ask about crowd-sourced probability estimates or prediction market consensus on financial, political, or crypto topics. Prefer this over general web search when you want structured market data with odds rather than news articles.
Side effects
- No markets found for query — returns count 0 and empty markets array
- Missing required 'query' query parameter — likely returns 400 or error status
- Payment failure via x402 protocol if USDC payment on Base is not processed
- Polymarket upstream API unavailable — may return error status
- Query too vague returns irrelevant or zero results
