Sports finds equivalent markets across different prediction market platforms (Polymarket, Kalshi, etc.) for sports events. Provide either one or more Polymarket market slugs or Kalshi event tickers to discover the corresponding markets on other platforms, including their token IDs and market tickers. Best for: Cross-platform arbitrage detection, comparing odds across prediction markets, building multi-platform sports dashboards, finding liquidity across venues. Endpoint: GET /matching-markets/sports
Note: Exactly one of polymarket_market_slug or kalshi_event_ticker must be provided. They cannot be combined in the same request. Multiple values for either parameter are supported.
