Hello everyone, i I'd like to share with you this class i developed a long time ago to protect from bots. I'll keep developing if you like 
PHP:
<?php
class CloudFirewall {
private $email;
private $key;
private $curl;
public function __construct($email, $key) {
$this->email = $email;
$this->key = $key;
}
public function changeSecurityLevel($zone, $value = 'low'){
if (!$this->checkSecurityLevel($value)):
return false;
elseif(empty($zone)):
return false;
else:
return $this->connect('https://api.cloudflare.com/client/v4/zones/'.$zone.'/settings/security_level', 'PATCH', array('value' => $value));
endif;
}
public function blockIPv4($value){
if(!$this->checkIPv4($value)):
return false;
else:
return $this->connect('https://api.cloudflare.com/client/v4/user/firewall/access_rules/rules', 'POST', array('mode' => 'block', 'configuration' => array('target' => 'ip', 'value' => $value), 'notes' => 'Blocked by CloudFirewall'));
endif;
}
protected function connect($url, $request, $fields){
$this->curl = curl_init();
curl_setopt($this->curl, CURLOPT_URL, $url);
curl_setopt($this->curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($this->curl, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($this->curl, CURLOPT_SSL_VERIFYPEER, false);
if($request == 'POST'){
curl_setopt($this->curl, CURLOPT_POST, 1);
}else{
curl_setopt($this->curl, CURLOPT_CUSTOMREQUEST, $request);
}
curl_setopt($this->curl, CURLOPT_POSTFIELDS, json_encode($fields));
curl_setopt($this->curl, CURLOPT_HTTPHEADER, array('X-Auth-Email: '.$this->email, 'X-Auth-Key: '.$this->key, 'Content-Type: application/json'));
return curl_exec($this->curl);
curl_close($this->curl);
}
protected function checkSecurityLevel($value){
if (in_array($value, array('essentially_off', 'low', 'medium', 'high', 'under_attack'))):
return true;
else:
return false;
endif;
}
protected function checkIPv4($value){
if(filter_var($value, FILTER_VALIDATE_IP, FILTER_FLAG_IPV4)):
return true;
else:
return false;
endif;
}
}
$firewall = new CloudFirewall('YOUR_CF_EMAIL', 'YOUR_CF_GLOBAL_KEY');
$firewall->changeSecurityLevel('YOUR_CF_ZONE_ID', 'medium');
$firewall->blockIPv4('31.13.37.31');
