To solve CAPTCHAs like reCAPTCHA with automation tools or CAPTCHA-solving services like CaptchaAI, you need two things:

1. The sitekey
    

2. The website URL where the CAPTCHA is embedded
    

This short guide will show you how to find the sitekey on any webpage and use it with CaptchaAI’s API to solve reCAPTCHA v2/v3 challenges.

 

🤔 What is a Sitekey?

A sitekey is a public identifier used by CAPTCHA services (like Google reCAPTCHA) to render a CAPTCHA on a web page. It tells the CAPTCHA API which site is making the request and how to serve the challenge.

CaptchaAI uses the sitekey to generate a valid token that you can submit in your automated request or form.

🔧 Tools You Need

To find the sitekey, you’ll need:

• A web browser (preferably Chrome or Firefox)
   

• Built-in Developer Tools (press F12 or right-click → Inspect)
   

• Basic HTML knowledge (optional)

 

🕵️‍♂️ How to Find the Sitekey – Step-by-Step

✅ Example: Google reCAPTCHA v2

 

Go to the Target Website
Visit the page where the reCAPTCHA appears.
 

Open Developer Tools
 

• Right-click on the page and select Inspect
   

• Or press Ctrl + Shift + I (Windows/Linux) or Cmd + Option + I (Mac)
   

Search for the Sitekey
 

• In the Elements tab, press Ctrl + F
   

• Search for:

data-sitekey

 

Copy the Sitekey

 

You’ll find HTML like:

🛠️ Submit to CaptchaAI API

Once you have the sitekey and the page URL, you're ready to submit your request.
