$context = stream_context_create($opt);
$params['timestamp'] = number_format(microtime(true)*1000,0,'.','');
$query = http_build_query($params, '', '&');
$signature = hash_hmac('sha256', $query, $secret);
$endpoint = "https://api.binance.com/wapi/v3/accountStatus.html?{$query}&signature={$signature}";

$res = json_decode(file_get_contents($endpoint, false, $context), true);
