Anti-Cloudflare Task

This task type is used to solve Cloudflare's JavaScript Challenge (the 'Checking your browser...' interstitial page). The solution provides a valid `cf_clearance` cookie.

How to Use the Solution

You must use the `userAgent` and `cookies` (specifically `cf_clearance`) from the solution in your subsequent requests to the target website.

Proxy is Required

This task type requires a proxy. The proxy's IP should ideally be in the same region as the target website's server for the best success rate.

1. Create Task

Use the `createTask` method to initiate the solving process. You must provide the `websiteURL` and a `proxy`.

Task Object Parameters

PropertyTypeRequiredDescription
typeStringRequiredMust be `AntiCloudflareTask`
websiteURLStringRequiredThe full URL of the page protected by a Cloudflare JS Challenge.
proxyStringRequiredYour proxy address in the format `http:login:password@ip:port`.

Run Sandbox Task

2. Get Result

After creating a task, use the `getTaskResult` method to check the status and retrieve the solution. Poll this endpoint every 5-10 seconds until the status is `completed`.

SDK Usage

# Coming soon: A simplified Python SDK
# pip install --upgrade captchasonic
#
# from captchasonic import CaptchaSonic
#
# client = CaptchaSonic(api_key="YOUR_API_KEY")
#
# solution = client.solve_cloudflare(
#   website_url="https://www.g2.com/products/discord/reviews",
#   proxy="http:login:[email protected]:8888"
# )
# print(f"CF Clearance Cookie: {solution.cookies['cf_clearance']}")
