example PHP

<?php
class Api {
    // API URL
    public $api_url = 'http://yourwebsite.com/api/v1'; 

    // Your API key
    public $api_key = '';

// Examples
$api = new Api();

# return all services
$services = $api->services(); 

# return user balance
$balance = $api->balance(); 

// add order
$order = $api->order(array('service' => 1, 'link' => 'http://example.com/test', 'quantity' => 100)); # Default

$order = $api->order(array('service' => 1, 'link' => 'http://example.com/test', 'comments' => "good pic\ngreat photo\n:)\n;)")); # Custom Comments

$order = $api->order(array('service' => 1, 'link' => 'http://example.com/test', 'quantity' => 100, 'runs' => 10, 'interval' => 60)); # Drip-feed

# return status, charge, remains, start count, order_id

# return orders status, charge, remains, start count, order_id
$statuses = $api->multi_status([12, 2, 13]);
