Endpoint
POSThttps://proxy.suverse.io/v1/data/kalshi-market-orderbookWhen to prefer
Use this endpoint when you need real-time order book depth (full price ladder and resting sizes) for a specific Kalshi prediction market, rather than just the top-of-book quoted price. Prefer this over general market summary endpoints when you need to assess liquidity, calculate market impact, or monitor spread changes.

- Market not currently active or trading halted may return empty levels
