How this service works
Polymarket prediction markets: the most traded open markets by 24-hour volume, or the markets matching a search, each with outcome prices (implied probability), best bid and ask, last trade, day change, volume, liquidity, end date, slug and CLOB token ids. Use to get the odds on an election, sports, crypto or news event, or to find a market before reading its order book.
Output
Returns a JSON object containing an array of matching prediction markets, each with: the market question, outcome names and their prices (implied probability 0–1), best bid and ask, last trade price, 24h volume, total volume, liquidity, day change, end date, active/closed status, URL slug, condition ID, and CLOB token IDs per outcome. Also includes the total count, the query used, and a timestamp.

Technical details
Endpoint
GEThttps://agent-data-tools.revmesh2074.workers.dev/polymarket/markets?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need current prediction market odds or probabilities on any event (elections, sports, crypto, macro) from Polymarket, or when you need to discover a market's slug and CLOB token IDs before placing orders or reading the full order book. Prefer this over general web search when you need structured, machine-readable probability data with volume and liquidity context.
Side effects
- Search returns empty array if query matches no open markets — try broader terms
- Limit parameter ignored if outside 1–20 range
- Stale data if Polymarket API is temporarily unavailable — checkedAt timestamp shows freshness
- Markets near resolution may show low liquidity or wide bid/ask spreads
- Closed markets only returned when closed=true is explicitly set
