Getting Started

DOM Tasks 'selenium-captcha' integrates with DeathByCaptcha to solve text CAPTCHAs and reCAPTCHA.

Before you begin:

👉 Create a DeathByCaptcha account. When you're ready to solve captchas, simply add credits to it; packages start at just $5.

The examples throughout this documentation use DeathByCaptcha and require the API credentials you'll obtain after registering.

Install the package:

pip install selenium-captcha

Install Selenium:

pip install selenium

If you're storing credentials as environment variables:

pip install python-dotenv

Each guide walks through authentication, solving the challenge, viewing the result, and handling incorrect captchas.






Solving Text captcha

Step 2 - I want to authenticate with...

Username and password authentication

Authenticate using your DeathByCaptcha account credentials.

import os

from captcha_solver import (
    CaptchaSolver,
    CaptchaSolverOptions,
    Credentials,
)

solver = CaptchaSolver(
    CaptchaSolverOptions(
        auth=Credentials(
            username=os.getenv("DBC_USERNAME"),
            password=os.getenv("DBC_PASSWORD"),
        )
    )
)

Credentials: Authenticates using your DeathByCaptcha username and password.

username: Your DeathByCaptcha account username.

password: Your DeathByCaptcha account password.

We recommend storing credentials as environment variables.

Step 3 - Solve captcha


Authtoken authentication

a) Setting up 2FA (authtoken) with DeathByCaptcha

  1. Log in to your account
  2. Go to User Settings at the bottom of the page
  3. Click on Authentication options
  4. Check the box "Enable this to use 2FA authentication" and click on SUBMIT
  5. Download Google Authenticator app, open it and click on the '+' button to add a new entry.
  6. Scan the QR code with your phone through the app and insert the code from the app into 'Verification code' field on the site.
  7. Copy and save your "Authentication Token" as an environment variable in your code and finally check the box "Enable this to use the token instead of User/Password combination" on the site. Authentication Token is ~156 characters long.

Sample token:

CQ6dd4DzLk5y830M2S16TnNEAqetNp2VmAPPx6CjM5wxRYpS0zm0CTMH38iBKfC3qf4tB9d2XIpzI184ZJv0G2RMUUcHi60372MRxUkE5A71bDopA3aQum2029LlLwX4R61hwr7fR51p6zRADdhT9u07e9v6

b) Initialize the solver:

import os

from captcha_solver import (
    CaptchaSolver,
    CaptchaSolverOptions,
    AuthToken,
)

solver = CaptchaSolver(
    CaptchaSolverOptions(
        auth=AuthToken(
            authtoken=os.getenv("DBC_AUTHTOKEN"),
        )
    )
)

AuthToken: Authenticates using your DeathByCaptcha Authentication Token.

authtoken: Your DeathByCaptcha Authentication Token.

We recommend storing it as an environment variable instead of hardcoding it into your application.

Solving Text Captchas

Use the solve() method to solve the challenge currently displayed on the page.

result = await solver.solve(
    ImageChallenge(
        page=driver,
        captcha=captcha,
        input=input_box,
    )
)

ImageChallenge: Represents an image CAPTCHA challenge.

page: A Selenium Webdriver instance.

Example:

driver = webdriver.Chrome()

captcha: A Selenium WebElement pointing to the CAPTCHA image.

Supported elements include:

  • <img>
  • <canvas>
  • <svg>
  • Container elements wrapping the CAPTCHA

Example:

captcha = driver.find_element(
    By.ID,
    "demoCaptcha_CaptchaImage",
)

input: A Selenium WebElement representing the textbox where the solved CAPTCHA should be entered.

Example:

input_box = driver.find_element(
    By.ID,
    "captchaCode",
)

Captcha solution metadata

The solve() method returns a SolveResult.

result = await solver.solve(
    ImageChallenge(
        page=driver,
        captcha=captcha,
        input=input_box,
    )
)

print(result)

Example output:

SolveResult(
    success=True,
    challenge="image",
    duration=4124,
    id="235368206",
    balance=10.081007,
)

The returned object contains:

success: Whether the operation completed successfully. If your target website still rejects the submitted CAPTCHA after automation continues, you should report it using report().

challenge: The type of challenge that was solved.

duration: Total execution time in milliseconds.

id: The CAPTCHA identifier assigned by DeathByCaptcha.

balance: Your remaining DeathByCaptcha balance after solving the challenge.

Reporting incorrect captchas:

Incorrect solutions can be reported to DeathByCaptcha so your account is credited appropriately.

result = await solver.solve(
    ImageChallenge(
        page=driver,
        captcha=captcha,
        input=input_box,
    )
)

await solver.report(result.id)

Your automation should determine whether the CAPTCHA was accepted by the target website.

For example, your application may:

Detect a validation message. Wait for a successful page navigation. Solve the captcha with the solve() function. Submit the form. Inspect for a warning if captcha was incorrect.

If the CAPTCHA was solved incorrectly, report it using:

await solver.report(result.id)

Please use this feature responsibly. Excessive reporting of correctly solved CAPTCHAs may result in account restrictions.

Error Handling

The SDK throws typed errors instead of generic Error objects.

Possible Errors

Error Description
NetworkError Network error, conexion lost.
TimeoutError The operation exceeded the configured timeout.
CaptchaSolverError The provider returned an error.

Design Principles

DOM Tasks follows a minimal design philosophy.

  • You own the browser.

  • You own the Selenium WebDriver.

  • You own the automation workflow.

  • The SDK performs one operation and immediately returns control.

  • The SDK never creates browser instances.

  • The SDK never manages browser lifecycle.

  • The SDK never hides Selenium APIs.

This allows the SDK to integrate naturally into existing Selenium automation without imposing its own framework or execution model.

Why DOM Tasks?

DOM Tasks is designed to feel like a native extension to SeleniumBase rather than another automation framework.

Instead of forcing you to learn a new API, it integrates directly into your existing workflow.

result = await solver.solve(
    RecaptchaChallenge(
        page=driver,
    )
)

Everything else remains under your control.

  • Use your own waits.
  • Use your own logging.
  • Use your own retry strategy.
  • Use your own browser configuration.
  • Use your own proxies.
  • Continue using SeleniumBase exactly as you already do.

The SDK focuses on solving CAPTCHAs and immediately returns control back to your automation.
