Hi
I have a php function which use captchakiller.com api to solve every captcha
I want to create a youtube account creator using that.
What i want to add to my function :
- use multiple api keys (because one api key = 30 captcha day)

Heres the function :

PHP:

<?php
	//
	// Configuration
	//
	//Your API key
	$api_key = 'B63A7848-D7B4-DE7E-E51E-CE1DD506AA78';

	//Path to captcha image
	$file = getcwd() . '/captcha.jpg';

	//Url to CaptchaKiller API
	$url = 'http://www.captchakiller.com/api.php';

	
	//
	// Functions
	//
	function upload_captcha($api_key, $file)
	{
		global $crl;

		$postdata = array(
				'method'	=> 'upload_captcha',
				'api_key'	=> $api_key,
				'file'		=> "@$file",
				'expire'	=> '300',
				'rights'	=> 'false'
				);

		curl_setopt ($crl, CURLOPT_POSTFIELDS, $postdata);

		$result = curl_exec($crl);
		$headers = curl_getinfo($crl);

		if ($headers['header_size'] == 0)
		{
			curl_close($crl);
			die('Upload Transaction failed');
		}
		else
		{
			echo 'Successfully uploaded captcha<br />';
		}

		//Parse captcha ID
		$pos = strpos($result, 'SUCCESS: captcha_id=');
		$captcha_id = 0;

		if($pos !== false)
		{
			$pattern = '([w-]+)';
			$matches = array();

			if(preg_match($pattern, substr($result, 20), $matches))	//20 = length of text before the ID
			{
				$captcha_id = $matches[0];
				echo 'Captcha ID: ' . $captcha_id . '<br />';
			}
			else
			{
				echo 'Could not find captcha id in: '' . $result . ''<br />';
			}
		}
		else
		{
			echo $result;
		}
		
		return $captcha_id;
	}

	function get_result($api_key, $captcha_id)
	{
		global $crl;

		//Send request for captcha result
		$postdata = array(
				'method'		=> 'get_result',
				'api_key'		=> $api_key,
				'captcha_id'	=> $captcha_id
				);

		curl_setopt ($crl, CURLOPT_POSTFIELDS, $postdata);

		$result = curl_exec($crl);
		$headers = curl_getinfo($crl);

		if ($headers['header_size'] == 0)
		{
			curl_close($crl);
			die('Get Result transaction failed');
		}
		
		return $result;
	}

	function process_captcha($api_key, $file, $url)
	{
		$captcha_id = upload_captcha($api_key, $file, $url);
		$captcha_result = '';
		
		if($captcha_id != 0)
		{
			echo 'Getting result';

			for($i = 0; $i < 20; $i++)
			{
				//Wait a few seconds before sending the next request
				sleep(5);

				//Get the result
				$result = get_result($api_key, $captcha_id);

				//Parse the result
				$pos_success = strpos($result, 'SUCCESS: captcha_result="');
				$pos_wait = strpos($result, 'WAIT: check back later');

				if($pos_success !== false)
				{
					$pattern = '(.*)';
					$matches = array();

					if(preg_match($pattern, substr($result, 25), $matches))	//24 = length of text before the result
					{
						$captcha_result = substr($matches[0], 0, -1);	//Trim off the trailing "
						echo '<br />Captcha Result: ' . $captcha_result . '<br />';
					}
					else
					{
						echo '<br />Could not find captcha result in: '' . $result . ''<br />';
					}
					break;
				}
				else if($pos_wait !== false)
				{
					//WAIT found, try again
					echo '.';
					continue;
				}
				else
				{
					//FAILURE found
					echo '<br />' . $result;
					break;
				}

				if($i == 19)
				{
					echo '<br />20 attempts have passed and still received WAIT<br />';
				}
			}
		}
		
		return $captcha_result;
	}
	
	//
	// Main program
	//
	// Start the cURL session
	$crl = curl_init();
	curl_setopt($crl, CURLOPT_URL, $url);
	curl_setopt($crl, CURLOPT_RETURNTRANSFER, 1);
	
	$captcha = process_captcha($api_key, $file, $url);

	//Close the cURL session
	curl_close($crl);
?>

Hi,

This seems very interesting, but depending on an external service to break your api could be dangerous, your effort is probably better spent developing a remote captcha script that you could have a community fill out for you.

Place API keys in the apikeys.txt file, one key per line. This code would run using one key 30 times. So if you got 10 keys, it will run 300 times. But it will upload the same captcha.jpg.

PHP:

<?php
    //
    // Configuration
    //
    //Your API key
    $keys = file("apikeys.txt");
    //$api_key = 'B63A7848-D7B4-DE7E-E51E-CE1DD506AA78';

    //Path to captcha image
    $file = getcwd() . '/captcha.jpg';

    //Url to CaptchaKiller API
    $url = 'http://www.captchakiller.com/api.php';

    
    //
    // Functions
    //
    function upload_captcha($api_key, $file)
    {
        global $crl;

        $postdata = array(
                'method'    => 'upload_captcha',
                'api_key'    => $api_key,
                'file'        => "@$file",
                'expire'    => '300',
                'rights'    => 'false'
                );

        curl_setopt ($crl, CURLOPT_POSTFIELDS, $postdata);

        $result = curl_exec($crl);
        $headers = curl_getinfo($crl);

        if ($headers['header_size'] == 0)
        {
            curl_close($crl);
            die('Upload Transaction failed');
        }
        else
        {
            echo 'Successfully uploaded captcha<br />';
        }

        //Parse captcha ID
        $pos = strpos($result, 'SUCCESS: captcha_id=');
        $captcha_id = 0;

    // Start the cURL session
    
    
    
    for($i=0;$i<count($keys);$i++){
    	for($j=0;$j<30;$j++){
	    	$crl = curl_init();
		    curl_setopt($crl, CURLOPT_URL, $url);
		    curl_setopt($crl, CURLOPT_RETURNTRANSFER, 1);
		    
		    $captcha = process_captcha($keys[$i], $file, $url);
		
		    //Close the cURL session
		    curl_close($crl);    		
    	}
    }

?>

The right way to do it, is to call api only when you download a new captcha image.

P.S. I'm sure captchakiller is tracking IPs accessing their service.
