Solve Unlimited Captchas with the Best Captcha Solver

CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a security measure designed to distinguish human users from automated bots. It often presents challenges such as image recognition, text distortion, or interactive puzzles that are easy for humans but difficult for bots. While CAPTCHAs protect websites from automated abuse, they can be a significant hurdle for legitimate automation and web scraping activities.

In this blog, we'll explore how to solve CAPTCHAs using Playwright with the Capsolver extension. Additionally, we'll look at solving reCAPTCHA using the Capsolver API with Python and Go.

What is CAPTCHA?

CAPTCHA is a security mechanism used by websites to prevent automated access and ensure that the user is a human. Common types include:

  • Image Recognition: Users are asked to select images matching a specific description.
  • Text Distortion: Users type distorted text displayed on the screen.
  • Interactive Challenges: Users complete tasks such as dragging sliders or solving puzzles.

Capsolver: Your Solution to CAPTCHA Challenges

Capsolver is a powerful tool designed to automatically solve various types of CAPTCHAs, including captcha and reCAPTCHA. It provides browser extensions and APIs for seamless integration into your web automation workflows.

Installing Playwright and Required Components

First, you need to install Playwright. You can do this via npm:

bash Copy
npm install playwright

Configuring the Capsolver Extension

  1. Download the Capsolver extension from here.
  2. Unzip it into the ./CapSolver.Browser.Extension directory at the root of your project.
  3. Adjust the configuration settings in ./assets/config.json. Ensure enabledForcaptcha is set to true and set captchaMode to token for automatic solving.

Example configuration change:

json Copy
{
  "enabledForcaptcha": true,
  "captchaMode": "token"
}

Setting Up Playwright to Solve captcha with Capsolver Extension

Below is an example script using Playwright to solve captcha with the Capsolver extension:

javascript Copy
const { chromium } = require('playwright');
const path = require('path');

(async () => {
  const extensionPath = path.join(__dirname, 'CapSolver.Browser.Extension');

  const browser = await chromium.launchPersistentContext('', {
    headless: false,
    args: [
      `--disable-extensions-except=${extensionPath}`,
      `--load-extension=${extensionPath}`
    ]
  });

  const page = await browser.newPage();
  await page.goto('https://site.example');

  // Locate the captcha checkbox or frame and interact accordingly
  await page.waitForSelector('selector-for-captcha', { state: 'visible' });
  await page.click('selector-for-captcha');

  // Add additional steps as per your requirement
  // ...

  await browser.close();
})();

Solving reCAPTCHA with Capsolver API

For reCAPTCHA, you can use the Capsolver API. Here are examples in Python and Go.

Python Example

python Copy
import requests
import time

api_key = "YOUR_API_KEY"
site_key = "6Le-wvkSAAAAAPBMRTvw0Q4Muexq9bi0DJwx_mJ-"
site_url = "https://www.google.com/recaptcha/api2/demo"

def capsolver():
    payload = {
        "clientKey": api_key,
        "task": {
            "type": 'ReCaptchaV2TaskProxyLess',
            "websiteKey": site_key,
            "websiteURL": site_url
        }
    }
    res = requests.post("https://api.capsolver.com/createTask", json=payload)
    resp = res.json()
    task_id = resp.get("taskId")
    if not task_id:
        print("Failed to create task:", res.text)
        return
    print(f"Got taskId: {task_id} / Getting result...")

    while True:
        time.sleep(3)
        payload = {"clientKey": api_key, "taskId": task_id}
        res = requests.post("https://api.capsolver.com/getTaskResult", json=payload)
        resp = res.json()
        status = resp.get("status")
        if status == "ready":
            return resp.get("solution", {}).get('gRecaptchaResponse')
        if status == "failed" or resp.get("errorId"):
            print("Solve failed! response:", res.text)
            return

token = capsolver()
print(token)

Go Example

go Copy
package main

	"bytes"
	"context"
	"encoding/json"
	"errors"
	"fmt"
	"io"
	"net/http"

type capSolverResponse struct {
	ErrorId          int32          `json:"errorId"`
	ErrorCode        string         `json:"errorCode"`
	ErrorDescription string         `json:"errorDescription"`
	TaskId           string         `json:"taskId"`
	Status           string         `json:"status"`
	Solution         map[string]any `json:"solution"`
}

func capSolver(ctx context.Context, apiKey string, taskData map[string]any) (*capSolverResponse, error) {
	uri := "https://api.capsolver.com/createTask"
	res, err := request(ctx, uri, map[string]any{
		"clientKey": apiKey,
		"task":      taskData,
	})
	if err != nil {
		return nil, err
	}
	if res.ErrorId == 1 {
		return nil, errors.New(res.ErrorDescription)
	}

	uri = "https://api.capsolver.com/getTaskResult"
	for {
		select {
		case <-ctx.Done():
			return res, errors.New("solve timeout")
		case <-time.After(time.Second):
			break
		}
		res, err = request(ctx, uri, map[string]any{
			"clientKey": apiKey,
			"taskId":    res.TaskId,
		})
		if err != nil {
			return nil, err
		}
		if res.ErrorId == 1 {
			return nil, errors.New(res.ErrorDescription)
		}
		if res.Status == "ready" {
			return res, err
		}
	}
}

func request(ctx context.Context, uri string, payload interface{}) (*capSolverResponse, error) {
	payloadBytes, err := json.Marshal(payload)
	if err != nil {
		return nil, err
	}
	req, err := http.NewRequestWithContext(ctx, "POST", uri, bytes.NewReader(payloadBytes))
	if err != nil {
		return nil, err
	}
	req.Header.Set("Content-Type", "application/json")
	client := &http.Client{}
	resp, err := client.Do(req)
	if err != nil {
		return nil, err
	}
	defer resp.Body.Close()
	responseData, err := io.ReadAll(resp.Body)
	if err != nil {
		return nil, err
	}
	capResponse := &capSolverResponse{}
	err = json.Unmarshal(responseData, capResponse)
	if err != nil {
		return nil, err
	}
	return capResponse, nil
}

func main() {
	apikey := "YOUR_API_KEY"
	ctx, cancel := context.WithTimeout(context.Background(), time.Second*120)
	defer cancel()

	res, err := capSolver(ctx, apikey, map[string]any{
		"type":       "ReCaptchaV2TaskProxyLess",
		"websiteURL": "https://www.google.com/recaptcha/api2/demo",
		"websiteKey": "6Le-wvkSAAAAAPBMRTvw0Q4Muexq9bi0DJwx_mJ-",
	})
	if err != nil {
		panic(err)
	}
	fmt.Println(res.Solution["gRecaptchaResponse"])
}
