# Futures order book

`GET /futures/orderbooks-snapshots`

## Request

- Base URL: `wss://ws.azbit.com`
- URL: `wss://ws.azbit.com/futures/orderbooks-snapshots`
- Auth: none declared

Not a REST call: this is the WebSocket **handshake**. Connect to the URL below and the exchange answers
`101 Switching Protocols`; everything after that is frames, not requests.

Public: no key, no signature.

Full-replace futures order-book snapshots for the pairs you name.

```json
{ "Method": "subscribe", "CurrencyPairs": ["BTCUSDT"] }
```

```json
{
  "currencyPairCode": "BTCUSDT",
  "asks": [{ "price": 64181.0, "quantity": 0.7 }],
  "bids": [{ "price": 64180.5, "quantity": 1.2 }]
}
```

This is the same shape as `GET /api/futures/trade/orderbook/{code}`. Each frame replaces the whole client
book, contains at most 20 levels per side, and is pushed at most every 500 ms per pair. Futures has no delta
channel: re-read this snapshot each time. Pair codes have no underscore; `/ping` is shared.

## Other responses

- `101`: Switching Protocols — the socket is open.
