Endpoint
GEThttps://mcpfax-markets.bowling-anthony.workers.dev/polymarket/marketWhen to prefer
Use this endpoint when you need granular, per-market detail about a specific Polymarket market including its live order book — as opposed to the polymarket_events endpoint which lists multiple events at once. Ideal when you already have a market ID or slug and need current prices, liquidity depth, and bid/ask data for trading decisions or analysis.

- Market may be resolved/closed and no longer have an active order book
