Usage
Choose environment
use KuCoin\Futures\SDK\KuCoinFuturesApi; // Switch to the sandbox environment KuCoinFuturesApi::setBaseUri('https://api-sandbox-futures.kucoin.com');
Debug mode & logging
use KuCoin\Futures\SDK\KuCoinFuturesApi; // Debug mode will record the logs of API and WebSocket to files in the directory "KuCoinFuturesApi::getLogPath()" according to the minimum log level "KuCoinFuturesApi::getLogLevel()". KuCoinFuturesApi::setDebugMode(true); // Logging in your code // KuCoinFuturesApi::setLogPath('/tmp'); // KuCoinFuturesApi::setLogLevel(Monolog\Logger::DEBUG); KuCoinFuturesApi::getLogger()->debug("I'm a debug message");
Examples
See the test case for more examples.
Example of API without
authentication
use KuCoin\Futures\SDK\PublicApi\Time; $api = new Time(); $timestamp = $api->timestamp(); var_dump($timestamp);
Example of API with
authentication
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
use KuCoin\Futures\SDK\Auth; use KuCoin\Futures\SDK\PrivateApi\Account; use KuCoin\Futures\SDK\Exceptions\HttpException; use KuCoin\Futures\SDK\Exceptions\BusinessException; // 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 = $api->getOverview(); var_dump($result); } catch (HttpException $e) { var_dump($e->getMessage()); } catch (BusinessException $e) { var_dump($e->getMessage()); }
Example of WebSocket feed
use KuCoin\Futures\SDK\Auth; use KuCoin\Futures\SDK\KuCoinFuturesApi; use KuCoin\Futures\SDK\PrivateApi\WebSocketFeed; use Ratchet\Client\WebSocket; use React\EventLoop\Factory; use React\EventLoop\LoopInterface; $auth = null; // Need to pass the Auth parameter when subscribing to a private channel($api->subscribePrivateChannel()). // Auth version v2 (recommend) // $auth = new Auth('key', 'secret', 'passphrase', Auth::API_KEY_VERSION_V2); // Auth version v1 // $auth = new Auth('key', 'secret', 'passphrase'); $api = new WebSocketFeed($auth); // Use a custom event loop instance if you like //$loop = Factory::create(); //$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('/contractMarket/ticker:ETHUSDTM'))); // Unsubscribe the channel // $ws->send(json_encode($api->createUnsubscribeMessage('/contractMarket/ticker:XBTUSDM'))); // Stop loop // $loop->stop(); }, function ($code, $reason) { echo "OnClose: {$code} {$reason}\n"; });
⚡️Coroutine HTTP client for asynchronous IO
See the benchmark, almost
20x
faster thancurl
.
pecl install swoole composer require swlib/saber
use KuCoin\Futures\SDK\Auth; use KuCoin\Futures\SDK\Http\SwooleHttp; use KuCoin\Futures\SDK\KuCoinFuturesApi; use KuCoin\Futures\SDK\PrivateApi\Order; use KuCoin\Futures\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()); } }); } });
