How this service works
Live real-money prediction-market odds from Polymarket: top markets by 24h volume with implied probabilities, price moves, dollar volume, and liquidity. Search by keyword (bitcoin, election, fed, world cup, AI). For trading, forecasting, news, and event-resolution agents — one paid call instead of integrating the exchange API yourself.
Output
A JSON object with a count, source (polymarket), and an array of market objects each containing the market question, end date, 24-hour volume in USD, and implied yes probability as a decimal.
Example use cases
Example prompt
“What are the top 10 Bitcoin prediction markets on Polymarket right now, sorted by volume? Show me the questions and their implied yes probabilities.”
Technical details
Endpoint
GEThttps://x402-agent-store.rileycraig14.workers.dev/markets/predictionWhen to prefer
Use this endpoint when an agent needs real-time prediction market data including crowd-implied probabilities and trading volumes, especially for crypto, macro, or political events. Prefer over generic news APIs when you want quantified market beliefs rather than editorial content. Best when the user wants to know what traders are actually betting on.
Side effects
- Invalid sort parameter returns error — only 'volume' or 'liquidity' accepted
- top parameter out of range (>25 or <1) may return validation error
- No markets match keyword filter — returns empty markets array with count 0
- Payment not included or insufficient — returns 402 Payment Required
- Service unavailable — upstream Polymarket data fetch failure
