### Example Authenticated Request

Source: https://github.com/suenot/okx-docs-markdown/blob/main/docs/authentication.md

A Python example demonstrating how to construct and send an authenticated GET request to the `/api/v5/account/balance` endpoint.

```APIDOC
## Example Request

This example shows how to make an authenticated GET request to the `/api/v5/account/balance` endpoint.

### Method
GET

### Endpoint
`/api/v5/account/balance`

### Parameters
#### Query Parameters
None

#### Request Body
None

### Request Example
```python
import requests
import time
from datetime import datetime
import hmac
import base64

# API credentials
api_key = "YOUR-API-KEY"
secret_key = "YOUR-SECRET-KEY"
passphrase = "YOUR-PASSPHRASE"

def sign(timestamp, method, request_path, body, secret_key):
    message = timestamp + method + request_path + body
    mac = hmac.new(
        bytes(secret_key, encoding='utf8'),
        bytes(message, encoding='utf-8'),
        digestmod='sha256'
    )
    d = mac.digest()
    return base64.b64encode(d).decode()

# Request details
timestamp = datetime.utcnow().isoformat(timespec='milliseconds') + 'Z'
method = 'GET'
request_path = '/api/v5/account/balance'
body = ''

# Generate signature
signature = sign(timestamp, method, request_path, body, secret_key)

# Headers
headers = {
    'OK-ACCESS-KEY': api_key,
    'OK-ACCESS-SIGN': signature,
    'OK-ACCESS-TIMESTAMP': timestamp,
    'OK-ACCESS-PASSPHRASE': passphrase
}

# Make request
url = 'https://www.okx.com' + request_path
response = requests.get(url, headers=headers)
print(response.json())
```

### Response
#### Success Response (200)
- **code** (string) - "0" indicates success.
- **data** (array) - An array of account balance objects.

#### Response Example
```json
{
  "code": "0",
  "data": [
    {
      "adjEq": "100.5",
      "availEq": "100.5",

### OKX PHP SDK WebSocket Server Setup

Source: https://github.com/suenot/okx-docs-markdown/blob/main/docs/sdk/php.md

Demonstrates how to configure and start a WebSocket server using the OKX PHP SDK for receiving real-time data. It includes options for logging, server address, heartbeat, and data refresh intervals.

```php
<?php
use Lin\Okex\OkexWebSocketV5;

$okex = new OkexWebSocketV5();

// Конфигурация WebSocket сервера
$okex->config([
    // Включить логирование
    'log' => true,
    
    // Адрес и порт демона (по умолчанию 0.0.0.0:2207)
    'global' => '127.0.0.1:2207',
    
    // Время сердцебиения (по умолчанию 20 секунд)
    'ping_time' => 20,
    
    // Время мониторинга подписок (по умолчанию 2 секунды)
    'listen_time' => 2,
    
    // Время обновления данных (по умолчанию 0.1 секунды)
    'data_time' => 0.1,
    
    // Размер очереди сообщений (по умолчанию 100)
    'queue_count' => 100,
]);

// Запуск сервера
$okex->start();

```

### Example Authenticated GET Request (Python)

Source: https://github.com/suenot/okx-docs-markdown/blob/main/docs/authentication.md

This Python script demonstrates how to make an authenticated GET request to the OKX API. It includes generating the current timestamp, constructing the request path and body, signing the request using the provided `sign` function, and setting the necessary authentication headers.

```python
import requests
import time
from datetime import datetime

# Assume sign function is defined as above
def sign(timestamp, method, request_path, body, secret_key):
    message = timestamp + method + request_path + body
    mac = hmac.new(
        bytes(secret_key, encoding='utf8'),
        bytes(message, encoding='utf-8'),
        digestmod='sha256'
    )
    d = mac.digest()
    return base64.b64encode(d).decode()

# API credentials
api_key = "YOUR-API-KEY"
secret_key = "YOUR-SECRET-KEY"
passphrase = "YOUR-PASSPHRASE"

# Request details
timestamp = datetime.utcnow().isoformat()[:-3] + 'Z'
method = 'GET'
request_path = '/api/v5/account/balance'
body = ''

# Generate signature
signature = sign(timestamp, method, request_path, body, secret_key)

# Headers
headers = {
    'OK-ACCESS-KEY': api_key,
    'OK-ACCESS-SIGN': signature,
    'OK-ACCESS-TIMESTAMP': timestamp,
    'OK-ACCESS-PASSPHRASE': passphrase
}

# Make request
url = 'https://www.okx.com' + request_path
response = requests.get(url, headers=headers)
print(response.json())
```

# Assume OKXPublicWebSocketClient is defined elsewhere
# from okx_websocket import OKXPublicWebSocketClient 

async def main():
    client = OKXPublicWebSocketClient()
    await client.start()

if __name__ == "__main__":
    asyncio.run(main())
```

This snippet demonstrates how to initialize the OkexWebSocketV5 client, configure logging, subscribe to public channels like 'tickers', 'books', and 'candle5m' for a specific instrument (e.g., BTC-USDT), and authenticate for private channel subscriptions using API keys. It also shows how to continuously fetch subscribed data.

```php
<?php
use Lin\Okex\OkexWebSocketV5;

$okex = new OkexWebSocketV5();

// Конфигурация клиента
$okex->config([
    'log' => true,
]);

// Подписка на публичные каналы
$okex->subscribe([
    ["channel" => "tickers", "instId" => "BTC-USDT"],
    ["channel" => "books", "instId" => "BTC-USDT"],
    ["channel" => "candle5m", "instId" => "BTC-USDT"],
]);

// Подписка на приватные каналы
$okex->keysecret([
    'key' => 'your-api-key',
    'secret' => 'your-secret-key',
    'passphrase' => 'your-passphrase',
]);

$okex->subscribe([
    // Публичные каналы
    ["channel" => "tickers", "instId" => "BTC-USDT"],
    ["channel" => "books", "instId" => "BTC-USDT"],
    
    // Приватные каналы
    ["channel" => "account", "ccy" => "BTC"],
    ["channel" => "positions", "instType" => "FUTURES"],
    ["channel" => "orders", "instType" => "SPOT"],
]);

// Получение данных
while(true) {
