Basilisk - FaucetPay Captcha

Attention!

CapMonster Cloud uses built-in proxies by default — their cost is already included in the service. You only need to specify your own proxies in cases where the website does not accept the token or access to the built-in services is restricted.

If you are using a proxy with IP authorization, make sure to whitelist the address 65.21.190.34.

Request parameters

type<string>required

CustomTask

class<string>required

Basilisk

websiteURL<string>required

The address of the main page where the captcha is solved.

websiteKey<string>required

userAgent<string>optional

Browser User-Agent.
Pass only a valid UA from Windows OS. Currently it is: userAgentPlaceholder

How to find all required parameters for task creation

Manually

Open your website where the captcha appears in the browser.
Right-click on the captcha element and select Inspect.

websiteKey

In the Network tab, filter requests using keywords related to captchas, such as site_key. These requests will contain the site_key parameter – a value used to identify the website during the captcha solving process:

site-key-basilisk

Automatically

To automate parameter extraction, you can retrieve them via a browser (regular or headless, e.g., using Playwright) or directly from HTTP requests. Since dynamic parameter values are short-lived, it is recommended to use them immediately after retrieval.

Important!

The provided code snippets are basic examples for learning how to extract the required parameters. The exact implementation will depend on your captcha page, its structure, and the HTML elements and selectors used.

Show code (for browser)

// Look for an element with the data-sitekey attribute
const captchaElement = document.querySelector('[data-sitekey]');

  console.log('Found site-key:', siteKey);
} else {
  console.log('site-key not found');
}
