MTCaptcha Task

MTCaptcha: Solving MTCaptcha

This task type is used to solve MTCaptcha challenges. The solution provides a validation token.

1. Create Task

Use the `createTask` method to initiate the solving process. You must provide the `websiteURL` and the MTCaptcha `websiteKey`.

Task Object Parameters

Property	Type	Required	Description
`type`	String	Yes	Must be `MtCaptchaTaskProxyless`
`websiteURL`	String	Yes	The full URL of the page where the MTCaptcha is present.
`websiteKey`	String	Yes	The `data-mkey` or public key for the MTCaptcha instance.

Example Request

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

{
    "apiKey": "YOUR_API_KEY",
    "task": {
        "type": "MtCaptchaTaskProxyless",
        "websiteURL": "https://www.mtcaptcha.com/demo-p",
        "websiteKey": "MTPublic-tqNCRE0GS"
    }
}

Example Response

A successful creation request returns a taskId which you will use in the next step.

{
    "errorId": 0,
    "status": "idle",
    "taskId": "89a24cc1-33ed-4b12-8c46-8132044f1234"
}

2. Get Result

After creating a task, use the `getTaskResult` method to check the status and retrieve the solution. Poll this endpoint every 3-5 seconds until the status is `completed`.

Example Request

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

{
    "apiKey": "YOUR_API_KEY",
    "taskId": "89a24cc1-33ed-4b12-8c46-8132044f1234"
}

Example Success Response

When the task status becomes completed, the response will contain the solution object.

{
    "errorId": 0,
    "status": "completed",
    "solution": {
        "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ[...]dQ",
        "userAgent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/108.0.0.0 Safari/537.36"
    },
    "taskId": "89a24cc1-33ed-4b12-8c46-8132044f1234"
}
