What are the potential implications of exceeding the limit of 100 free requests per day for a non-commercial API like uTrace in PHP?

Exceeding the limit of 100 free requests per day for a non-commercial API like uTrace in PHP can result in the API denying further requests or potentially blocking your IP address. To solve this issue, you can implement rate limiting in your PHP code to ensure that you do not exceed the daily limit set by the API.

// Check if the number of requests exceeds the limit
$limit = 100;
$requests_made = // retrieve the number of requests made so far;

if ($requests_made >= $limit) {
    die('Daily request limit exceeded. Please try again tomorrow.');
}

// Make the API request here

// Update the number of requests made
$requests_made++;
