Output
Returns a JSON object containing an array of up to 40 Polymarket markets, each with: question text, outcome probabilities (prob_pct per outcome), liquidity in USD, 24-hour volume, total volume, market end date, and a direct URL to the Polymarket page. Also includes a 'how_to_read' explanation note, source attribution, and collection timestamp.
Example use cases
Election outcome probability check
“What probability is Polymarket currently assigning to the main candidates in the next major election? I want the odds, liquidity, and 24h volume for each relevant market.”
Macro event risk dashboard
“Give me a snapshot of Polymarket's top prediction markets right now — I want to see which geopolitical or economic events have the highest trading volume so I can gauge where uncertainty is concentrated.”
Pre-trade event risk filter
“Before I take a position, pull the current Polymarket odds on any markets related to central bank decisions or Fed rate moves — I need the probability and how much money is behind each outcome.”
Technical details
Endpoint
GEThttps://agentdatum.com/api/v1/d/polymarket-oddsWhen to prefer
Choose this endpoint when you need crowd-sourced, money-backed event probabilities rather than news sentiment or analyst forecasts. It is ideal for political, macro, and crypto event forecasting where prediction market prices lead traditional media. Prefer it over news APIs when you want quantified forward-looking probabilities with volume-backed confidence. It is not suitable if you need a specific single market by ID, historical odds, or order book depth.
Side effects
- Polymarket Gamma API unavailable — upstream dependency failure
- Stale data if collected_at timestamp is significantly behind real-time
- Market list may be incomplete if fewer than expected markets are active
- Duplicate market entries may appear in the response array (observed in example)
- No filtering or search parameters available — returns all markets in bulk
