Usage

Image to Text

A normal CAPTCHA is an image containing distorted text that can only be read by humans. to solve this type of CAPTCHA the user is required to enter the text of the image. You can use imageMemoryToText() function for local images or imageLinkToText() for images from the site. YOUR_API_KEY : You can find the API key here

import 'package:captcha_solver/captcha_solver.dart';

void main() async {

  /// Initiate query Properties
  String apiKey = 'YOUR_API_KEY';
  String imageMemory = 'lib/captcha.jpg';
  String imageLink = 'https://api.vk.com/captcha.php?sid=1';
  /// Initiate CaptchaSolver
  CaptchaSolver captchaSolver = CaptchaSolver(apiKey);
  /// Example of the request
  Map inputs = {
    "clientKey": apiKey,
    "task": {
      "type": "ImageToTextTask",
      "body": imageMemory // or imageLink
    }
  };
  /// Get captcha solution
  Map response = await captchaSolver.imageMemoryToText(inputs); // Or imageLinkToText()
  print('response: $response');
  if(response['status']=='ready') {
    print(response['solution']['text']);
  }
}

reCAPTCHA v2

reCAPTCHA v2 requires the user to check the "I'm not a robot" box and can offer them an image recognition challenge. YOUR_WEBSITE_KEY : reCAPTCHA website key - for more details : https://scraptcha.com/documentation/ YOUR_API_KEY : You can find the API key here

import 'package:captcha_solver/captcha_solver.dart';

void main() async {
  /// Initiate query Properties
  String apiKey = 'YOUR_API_KEY';
  String websiteURL = 'http://mywebsite.com/recaptcha/test.php';
  String websiteKey = 'YOUR_WEBSITE_KEY';
  /// Initiate CaptchaSolver
  CaptchaSolver captchaSolver = CaptchaSolver(apiKey);
  /// Example of the request
  Map inputs = {
    "clientKey": apiKey,
    "task": {
      "type": "RecaptchaV2TaskProxyless",
      "websiteURL": websiteURL,
      "websiteKey": websiteKey,
      "isInvisible": false
    }
  };
  /// Get captcha solution
  Map response = await captchaSolver.recaptcha(inputs);
  print('response: $response');
  if(response['status']=='ready') {
    print(response['solution']['gRecaptchaResponse']);
  }
}

reCAPTCHA V3

reCAPTCHA v3 is somewhat similar to reCAPTCHA V2. reCAPTCHA V3 works in the background, does not require user interaction and generates a score based on user behavior. The higher the score, the more likely the user is human.

import 'package:captcha_solver/captcha_solver.dart';

void main() async {

  /// Initiate query Properties
  String apiKey = 'YOUR_API_KEY';
  String websiteURL = 'http://mywebsite.com/recaptcha/test.php';
  String websiteKey = 'YOUR_WEBSITE_KEY';
 /// Initiate CaptchaSolver
  CaptchaSolver captchaSolver = CaptchaSolver(apiKey);
/// Example of the request
  Map inputs = {
  "clientKey": apiKey,
  "task": {
  "type": "RecaptchaV3TaskProxyless", // type of captcha
  "websiteURL": websiteURL,
  "websiteKey": websiteKey,
  "minScore": 0.3,
  "pageAction": "verify",
  "isEnterprise": false
  }
};
  /// Get captcha solution
  Map response = await captchaSolver.recaptcha(inputs);
  print('response: $response');
  if(response['status']=='ready') {
    print(response['solution']['gRecaptchaResponse']);
  }
}

FunCAPTCHA - Arkose Labs

This type of task solves the arkoselabs.com conundrum in our worker browsers. You submit the public key and the website address then you will receive a token when the task is completed. This is the token you will need to submit your forms with Arkoselabs captcha.

import 'package:captcha_solver/captcha_solver.dart';

void main() async {

  /// Initiate query Properties
  String apiKey = 'YOUR_API_KEY';
  String websiteURL = 'https://account.battle .net/creation/flow/creation-full';
  String websitePublicKey = 'YOUR_WEBSITE_KEY';
 /// Initiate CaptchaSolver
  CaptchaSolver captchaSolver = CaptchaSolver(apiKey);
/// Example of the request
  Map inputs = {
    "clientKey": "YOUR_API_KEY",
    "task": {
      "type": "FunCaptchaTaskProxyless",
      "websitePublicKey": websitePublicKey,
      "websiteURL": websiteURL
  }
};
  /// Get captcha solution
  Map response = await captchaSolver.recaptcha(inputs);
  print('response: $response');
  if(response['status']=='ready') {
    print(response['solution']['token']);
  }
}

hCAPTCHA

HCAPTCHA is a most popular reCAPTCHA alternative. The properties of this task are the same as reCAPTCHA except for the type property.

import 'package:captcha_solver/captcha_solver.dart';

void main() async {
  /// Initiate query Properties
  String apiKey = 'YOUR_API_KEY';
  String websiteURL = 'https://hcaptcha.com/';
  String websiteKey = 'YOUR_WEBSITE_KEY';
  /// Initiate CaptchaSolver
  CaptchaSolver captchaSolver = CaptchaSolver(apiKey);
  /// Example of the request
  Map inputs = {
    "clientKey": apiKey,
    "task": {
      "type": "HCaptchaTaskProxyless",
      "websiteURL": websiteURL,
      "websiteKey": websiteKey,
  
    }
  };
  /// Get captcha solution
  Map response = await captchaSolver.recaptcha(inputs);
  print('response: $response');
  if(response['status']=='ready') {
    print(response['solution']['gRecaptchaResponse']);
  }
}
