# Orderbook

# Realtime Order Book

**Route:** `GET /api/v1/orderbook`

Returns the latest available order-book snapshot for a symbol. The current implementation reads Redis keys per venue and can return one or more venue snapshots.

## Query Parameters

* `symbol` required
* `source` optional, for example `kalshi` or `polymarket`

## Example

```http theme={null}
GET /api/v1/orderbook?symbol=KXBTCD-26JUN1420&source=kalshi
```

## Response Notes

* The response returns `orderbooks` as an array.
* Without `source`, the handler checks both supported venues.
* This route is a current-state snapshot, not a historical replay surface.
