Prediction Market Snapshot

Searches Polymarket and Kalshi prediction markets with one query, returning both venues' open markets side by side.

Overview

Searches Polymarket and Kalshi prediction markets with one query, returning both venues' open markets side by side. Composite: one call runs polymarket-markets + kalshi-markets in parallel with the same free-text query and returns merged {polymarket: [], kalshi: []} lists: questions, tickers, implied outcome prices (0-1), volume, liquidity, and end dates from both venues. Data-only listing of public market data; no probability advice, no order entry, no trading. Use it as a cross-venue market search or event odds listing bundle.
