Kuna REST API Reference

https://kuna.io/documents/api

Contributing

To create new endpoint - create issue or create pull request

Install

composer require cryptopupua/kuna-api 1.1.*

Usage

require __DIR__.'/vendor/autoload.php';

use cryptopupua\KunaApi\Api;
use cryptopupua\KunaApi\Exception\IncorrectResponseException;
use cryptopupua\KunaApi\KunaApi;
use cryptopupua\KunaApi\Model\History;
use cryptopupua\KunaApi\Model\MyAccount;
use cryptopupua\KunaApi\Model\Order;
use cryptopupua\KunaApi\Model\Ticker;


$api = new KunaApi(
    'https://kuna.io',
    'public key',
    'secret key'
);
$timestamp = $api->shared()->timestamp();

Mapping

Each endpoint response (exclude: timestamp) can be received as array or as object.

To use mapping response to object set parameter $mapping to true.

$issue = $api->signed()->activeOrders(Http::PAIR_ETHUAH, true);

// Result
[
    {
    class madmis\KunaApi\Model\Order {
        protected $id => 10003
        protected $side => "sell"
        protected $ordType => "limit"
        protected $price => 10000
        protected $avgPrice => 0
        protected $state => "wait"
        protected $market => "ethuah"
        protected $createdAt => DateTime
        protected $volume => 0.01
        protected $volume => 0.01
        protected $remainingVolume => 0.01
        protected $executedVolume => 0
        protected $tradesCount => 0
      }
    
    },
    ...
] 

Error handling

Each client request errors wrapped to custom exception madmis\ExchangeApi\Exception\ClientException

class madmis\ExchangeApi\Exception\ClientException {
  private $request => class GuzzleHttp\Psr7\Request
  private $response => NULL
  protected $message => "cURL error 7: Failed to connect to 127.0.0.1 port 8080: Connection refused (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)"
  ...
}

ClientException contains original request object and response object if response available

class madmis\ExchangeApi\Exception\ClientException {
  private $request => class GuzzleHttp\Psr7\Request 
  private $response => class GuzzleHttp\Psr7\Response {
    private $reasonPhrase => "Unauthorized"
    private $statusCode => 401
    ...
  }
  protected $message => "Client error: 401"
  ...  
}

So, to handle errors use try/catch

try {
    $api->signed()->activeOrders(Http::PAIR_ETHUAH, true);
} catch (madmis\ExchangeApi\Exception\ClientException $ex) {
    // any actions (log error, send email, ...) 
}

Running the tests

To run the tests, you'll need to install phpunit. Easiest way to do this is through composer.

composer install

Running Unit tests

php vendor/bin/phpunit -c phpunit.xml.dist
