Cloudflare: solving Challenge

TIP

Create the task with the createTask method and get the result with the getTaskResult method.

Note

Proxy is necessary, please use Static proxy or Sticky proxy instead of Rotating proxy.
Support custom userAgent, please keep it the same as the one you are using.
If you fail to get the solution, your IP may be blocked, please try to change your proxy.
You have to use the TLS request library to request the target website.

The task type type is as follows

AntiCloudflareTask

Create Task

Create the task with the createTask.

Task Object Structure

Properties	Type	Required	Description
type	String	Required	`AntiCloudflareTask`
websiteURL	String	Required	The address of the target page.
proxy	String	Required	Your Static proxy or Sticky proxy. Learn Using proxies
userAgent	String	Optional	The `user-agent` you used to request the target website. Only Chrome’s userAgent is supported

Example Request

POST https://api.capsolver.com/createTask
Host: api.capsolver.com
Content-Type: application/json

{
  "clientKey": "YOUR_API_KEY",
  "task": {
    "type": "AntiCloudflareTask",
    "websiteURL": "https://www.yourwebsite.com",
    "userAgent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/141.0.0.0 Safari/537.36",
    "proxy": "ip:port:user:pass"
  }
}

Example Response

{
  "errorId": 0,
  "status": "idle",
  "taskId": "df944101-64ac-468d-bc9f-41baecc3b8ca"
}

Getting Result

Use the getTaskResult method to get the recognition results

Depending on the website and proxy, you will get the results within the interval of 2s to 20s

Example Request

POST https://api.capsolver.com/getTaskResult
Host: api.capsolver.com
Content-Type: application/json

{
  "clientKey": "YOUR_API_KEY",
  "taskId": "df944101-64ac-468d-bc9f-41baecc3b8ca"
}

Example Response

{
  "errorId": 0,
  "taskId": "df944101-64ac-468d-bc9f-41baecc3b8ca",
  "status": "ready",
  "errorCode": "",
  "errorDescription": "",
  "solution": {
    "cookies": {
        "cf_clearance": "Bcg6jNLzTVaa3IsFhtDI.e4_LX8p7q7zFYHF7wiHPo...uya1bbdfwBEi3tNNQpc"
    },
    "token": "Bcg6jNLzTVaa3IsFhtDI.e4_LX8p7q7zFYHF7wiHPo...uya1bbdfwBEi3tNNQpc",
    "userAgent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/139.0.0.0 Safari/537.36"
  }
}

Use SDK Request

# pip install --upgrade capsolver
# export CAPSOLVER_API_KEY='...'
 
import capsolver
 
# capsolver.api_key = "..."
solution = capsolver.solve({
  "type": "AntiCloudflareTask",
  "websiteURL": "https://www.yourwebsite.com",
  "proxy": "ip:port:user:pass"
})
