PHP

Check and report from any PHP application.

Works in any PHP application with the curl extension, which is nearly all of them. For WordPress there is a ready-made must-use plugin.

Check an address

function isipsafe_score(string $ip): int {
    $ch = curl_init('https://isipsafe.com/api/v1/check?ip=' . urlencode($ip));
    curl_setopt_array($ch, [CURLOPT_RETURNTRANSFER => true, CURLOPT_TIMEOUT => 3]);
    $body = curl_exec($ch);
    curl_close($ch);
    $data = json_decode((string) $body, true);
    return (int) ($data['data']['abuseConfidenceScore'] ?? 0); // 0 if the lookup failed
}

if (isipsafe_score($_SERVER['REMOTE_ADDR']) >= 75) {
    http_response_code(403);
    exit('Access denied');
}

Report an address

function isipsafe_report(string $ip, string $categories, string $comment = ''): void {
    $ch = curl_init('https://isipsafe.com/api/v1/report?key=' . urlencode(getenv('ISIPSAFE_KEY') ?: ''));
    curl_setopt_array($ch, [
        CURLOPT_POST => true,
        CURLOPT_POSTFIELDS => http_build_query(['ip' => $ip, 'categories' => $categories, 'comment' => $comment]),
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_TIMEOUT => 5,
    ]);
    curl_exec($ch);
    curl_close($ch);
}

isipsafe_report('203.0.113.50', 'web-app-attack,brute-force', '40 failed logins in 5 minutes');
