This is your credit balance. Even if you are an anonymous user, you are given some credits to spend. Every IP address has its own account and it is provided with free credits that can be used to pay for Online Domain Tools services. Moreover, credit balance is reset every day. This is why we call them Daily Credits. Registered users have higher Daily Credits amounts and can even increase them by purchasing subscriptions.
Besides Daily Credits, all accounts, including IP address accounts of anonymous users, have their credit Wallet. Wallet credits are not reset on a daily basis, but they are only spent when a user has not enough Daily Credits. Registered users can buy credits to their wallets. All IP address accounts are created with an initial Wallet balance of 3.00. Once IP address account spends credits from its Wallet, it can not be charged again. This should allow new users to try most of Online Domain Tools services without registration.

Example #1 A ctype_upper() example (using the default locale)
<?php
$strings = array('AKLWC139', 'LMNSDO', 'akwSKWsm');
foreach ($strings as $testcase) {
if (ctype_upper($testcase)) {
echo "The string $testcase consists of all uppercase letters.\n";
} else {
echo "The string $testcase does not consist of all uppercase letters.\n";
}
}
?>
The above example will output:
The string AKLWC139 does not consist of all uppercase letters. The string LMNSDO consists of all uppercase letters. The string akwSKWsm does not consist of all uppercase letters.
