# Get Market Orderbook

`GET /markets/{ticker}/orderbook`

## Request

- Base URL: `https://external-api.kalshi.com/trade-api/v2`
- URL: `https://external-api.kalshi.com/trade-api/v2/markets/{ticker}/orderbook`
- Auth: none declared

Endpoint for getting the current order book for a specific market.  The order book shows all active bid orders for both yes and no sides of a binary market. It returns yes bids and no bids only (no asks are returned). This is because in binary markets, a bid for yes at price X is equivalent to an ask for no at price (100-X). For example, a yes bid at 7¢ is the same as a no ask at 93¢, with identical contract sizes.  Each side shows price levels with their corresponding quantities and order counts, organized from best to worst prices.

## Path parameters

- `ticker` string, required

## Query parameters

- `depth` integer
