How this service works
List and search active Polymarket prediction markets with outcome probabilities, liquidity, volume, end dates, and URLs. Data-only market research for event odds — no trade signals, custody, or execution.
Output
Returns a list of active Polymarket prediction markets matching the query, each including the market name/question, outcome probabilities (e.g. Yes/No percentages), liquidity amount, trading volume, market end/resolution date, and a direct URL to the market on Polymarket.
Example use cases
Election odds research
“Pull up the current Polymarket prediction markets for the 2024 US election — I want to see the outcome probabilities, how much liquidity each market has, and when they close.”
Crypto event probability lookup
“Search Polymarket for any active prediction markets about Bitcoin ETF approval or SEC crypto regulation and show me the latest probabilities and volume.”
High-volume market discovery
“List the most active Polymarket markets right now sorted by trading volume — I want to see what topics are getting the most attention with their current odds and end dates.”
Technical details
Endpoint
POSThttps://x402.agentutility.ai/prediction-marketsWhen to prefer
Use this endpoint when an agent needs to research event probabilities or crowd-sourced forecasts from Polymarket without executing trades. Ideal for summarizing current market sentiment on political, financial, or world events. Prefer this over direct Polymarket API access when the agent operates in an x402 USDC-payment environment and needs structured, pre-processed market data. Not suitable for executing trades, managing positions, or real-time price streaming.
Side effects
- No markets found matching the search query — returns empty list
- Polymarket data source temporarily unavailable — service error
- Overly broad query returns too many low-relevance markets
- Market data may have slight latency vs real-time Polymarket prices
- Payment failure via x402 protocol if USDC balance insufficient
