Requirements

Install

Install package via Composer.

composer require "kucoin/kucoin-php-sdk:~1.1.0"

Usage

Choose environment

// Switch to the sandbox environment
KuCoinApi::setBaseUri('https://api.kucoin.com');

Debug mode & logging

// Debug mode will record the logs of API and WebSocket to files in the directory "KuCoinApi::getLogPath()" according to the minimum log level "KuCoinApi::getLogLevel()".
KuCoinApi::setDebugMode(true);

// Logging in your code
// KuCoinApi::setLogPath('/tmp');
// KuCoinApi::setLogLevel(Monolog\Logger::DEBUG);
KuCoinApi::getLogger()->debug("I'm a debug message");

Examples

See the test case for more examples.

Example of API without authentication

use KuCoin\SDK\PublicApi\Time;

$api = new Time();
$timestamp = $api->timestamp();
var_dump($timestamp);

Note

To reinforce the security of the API, KuCoin upgraded the API key to version 2.0, the validation logic has also been changed. It is recommended to create(https://www.kucoin.com/account/api) and update your API key to version 2.0. The API key of version 1.0 will be still valid until May 1, 2021

Example of API with authentication

use KuCoin\SDK\PrivateApi\Account;
use KuCoin\SDK\Exceptions\HttpException;
use KuCoin\SDK\Exceptions\BusinessException;
use KuCoin\SDK\Auth;

// Auth version v2 (recommend)
$auth = new Auth('key', 'secret', 'passphrase', Auth::API_KEY_VERSION_V2);
// Auth version v1
// $auth = new Auth('key', 'secret', 'passphrase');

$api = new Account($auth);

try {
    $result = $api->getList(['type' => 'main']);
    var_dump($result);
} catch (HttpException $e) {
    var_dump($e->getMessage());
} catch (BusinessException $e) {
    var_dump($e->getMessage());
}

Example of WebSocket feed

use KuCoin\SDK\Auth;
use KuCoin\SDK\PrivateApi\WebSocketFeed;
use Ratchet\Client\WebSocket;
use React\EventLoop\Loop;
use React\EventLoop\LoopInterface;

$auth = null;
// Need to pass the Auth parameter when subscribing to a private channel($api->subscribePrivateChannel()).
// $auth = new Auth('key', 'secret', 'passphrase');
$api = new WebSocketFeed($auth);

// Use a custom event loop instance if you like
//$loop = Loop::get();
//$loop->addPeriodicTimer(1, function () {
//    var_dump(date('Y-m-d H:i:s'));
//});
//$api->setLoop($loop);

$query = ['connectId' => uniqid('', true)];
$channels = [
    ['topic' => '/market/ticker:KCS-BTC'], // Subscribe multiple channels
    ['topic' => '/market/ticker:ETH-BTC'],
];

$api->subscribePublicChannels($query, $channels, function (array $message, WebSocket $ws, LoopInterface $loop) use ($api) {
    var_dump($message);

    // Subscribe another channel
    // $ws->send(json_encode($api->createSubscribeMessage('/market/ticker:LTC-BTC')));

    // Unsubscribe the channel
    // $ws->send(json_encode($api->createUnsubscribeMessage('/market/ticker:ETH-BTC')));

    // Stop loop
    // $loop->stop();
}, function ($code, $reason) {
    echo "OnClose: {$code} {$reason}\n";
});

Add custom options

use KuCoin\SDK\PublicApi\Time;

$api = new Time(null, new GuzzleHttp([
    'curl' => [ // custom cURL options: https://www.php.net/manual/en/function.curl-setopt
        CURLOPT_TCP_NODELAY => true, // Disable TCP's Nagle algorithm, which tries to minimize the number of small packets on the network.
        // ...
    ],
]));
$timestamp = $api->timestamp();
var_dump($timestamp);

use KuCoin\SDK\Auth;
use KuCoin\SDK\Http\GuzzleHttp;
use KuCoin\SDK\KuCoinApi;
use KuCoin\SDK\PrivateApi\WebSocketFeed;
use Ratchet\Client\WebSocket;
use React\EventLoop\Factory;
use React\EventLoop\LoopInterface;

$api = new WebSocketFeed(
    null,
    new GuzzleHttp([
        'curl' => [ // Custom cURL options: https://www.php.net/manual/en/function.curl-setopt
            CURLOPT_TCP_NODELAY => true, // Disable TCP's Nagle algorithm, which tries to minimize the number of small packets on the network.
            // ...
        ],
    ])
);
$query = ['connectId' => uniqid('', true)];
$channels = [
    ['topic' => '/market/ticker:KCS-BTC'],
    ['topic' => '/market/ticker:ETH-BTC'],
];
$options = ['tcp' => ['tcp_nodelay' => true]]; // Custom socket context options: https://www.php.net/manual/zh/context.socket
$api->subscribePublicChannels($query, $channels, function (array $message, WebSocket $ws, LoopInterface $loop) use ($api) {
    var_dump($message);
}, function ($code, $reason) {
    echo "OnClose: {$code} {$reason}\n";
}, $options);

⚡️Coroutine HTTP client for asynchronous IO

See the benchmark, almost 20x faster than curl.

pecl install swoole
composer require swlib/saber

use KuCoin\SDK\Auth;
use KuCoin\SDK\Http\SwooleHttp;
use KuCoin\SDK\KuCoinApi;
use KuCoin\SDK\PrivateApi\Order;
use KuCoin\SDK\PublicApi\Time;

// Require PHP 7.1+ and Swoole 2.1.2+
// Require running in cli mode

go(function () {
    $api = new Time(null, new SwooleHttp);
    $timestamp = $api->timestamp();
    var_dump($timestamp);
});

go(function () {
    // Auth version v2 (recommend)
    $auth = new Auth('key', 'secret', 'passphrase', Auth::API_KEY_VERSION_V2);
    // Auth version v1
    // $auth = new Auth('key', 'secret', 'passphrase');
    $api = new Order($auth, new SwooleHttp);
    // Create 50 orders CONCURRENTLY in 1 second
    for ($i = 0; $i < 50; $i++) {
        go(function () use ($api, $i) {
            $order = [
                'clientOid' => uniqid(),
                'price'     => '1',
                'size'      => '1',
                'symbol'    => 'BTC-USDT',
                'type'      => 'limit',
                'side'      => 'buy',
                'remark'    => 'ORDER#' . $i,
            ];
            try {
                $result = $api->create($order);
                var_dump($result);
            } catch (\Throwable $e) {
                var_dump($e->getMessage());
            }
        });
    }
});
