Usage

Instantiate the client

<?php

]);

Convert from one currency to another:

Check if the market is open:

if ($client->marketIsOpen())
{
    echo "Market is open";    
}

Check your usage / quota limit:

$client->quota();

Stream quote updates:

WebSocket quote streaming is only available on paid plans.

//Handle incoming price updates from the server
$client->onUpdate(function($symbol, $data)
{
    echo $symbol . ": " . $data["b"] . " " .$data["a"] . " " . $data["p"]."\n";
});

//Handle non-price update messages
$client->onMessage(function($message)
{
    echo $message;
});

//Connect to the server
$client->connect(function($client)
{
    //Subscribe to a single currency pair
    $client->subscribeTo('EUR/USD');

    //Subscribe to an array of currency pairs
    $client->subscribeTo([
        'GBP/JPY',
        'AUD/CAD',
        'EUR/CHF'
    ]);

    //Subscribe to all currency pairs
    $client->subscribeToAll();

    //Unsubscribe from a single currency pair
    $client->unsubscribeFrom('EUR/USD');

    //Unsubscribe from an array of currency pairs
    $client->unsubscribeFrom([
        'GBP/JPY',
        'AUD/CAD',
        'EUR/CHF'
    ]);

    //Unsubscribe from all currency pairs
