First, install the extension. The extension download link is:
https://chrome.google.com/webstore/detail/nocaptcha-solver/kkphlbgphimpedeckcepigahenlmpggc?utm_source=ext_sidebar&hl=zh-CN
Click here to download
After installing the extension, pin the NoCaptcha Solver extension to the extensions bar (for convenience) and then log in to your platform account. token is the token consumed, user name is the platform login account, i.e., email address.


Click Manage extensions or enter chrome://extensions/ into the extension page and click Service Worker.

Clicking will open the developer tools, at this point, switch to the network panel.

Open the website that needs to be cracked, such as https://democaptcha.com/demo-form-eng/recaptcha-2.html, and the extension will automatically start to crack reCaptcha or hCaptcha.


At this point, in the network column, you can get all the parameters needed for the captcha. Pay no attention to the extra object and do not submit this parameter.

{
    "sitekey": "6LfGqN0UAAAAAFdGo4OSj5Awi8hM_9kmR7VfXUP2",
    "referer": "https://democaptcha.com/demo-form-eng/recaptcha-2.html",
    "title": "reCAPTCHA 2 demo form | AntiCaptcha plugin demo forms",
    "size": "normal",
    "action": null,
    "s": null,
    "extra": {
        "origin": "chrome-plugin",
        "cb": null
    }
}
With this, all the parameters needed for cracking are obtained at once. The operation of hCaptcha is exactly the same as reCaptcha, so it is not repeated here.
