Solve Image Captchas with CapSolver

Image captchas are a common security measure used on websites to distinguish between human users and bots. They typically involve the user identifying specific elements within an image or series of images. In this blog post, we'll guide you through the process of solving image captchas using CapSolver.

What is an Image Captcha?

An image captcha is a type of challenge-response test used in computing to determine whether the user is human. The test involves one or more images from which the user is asked to identify or select specific elements. The aim is to prevent automated software or "bots" from carrying out tasks that should be performed by humans.

Solving Image Captchas with CapSolver

CapSolver provides a convenient and efficient way to solve image captchas. The process involves creating a task with the createTask method and providing the necessary parameters. Here's a step-by-step guide:

Step 1: Creating the Task

To create a task, you need to make a POST request to the endpoint. The request should include your API key and the task details. For an image captcha, the task type is ImageToTextTask. The task details should also include the base64 encoded content of the image. Here's an example of the request:

Content-Type: application/json
 "clientKey": "YOUR_API_KEY",
 "body": "base64_encoded_image_content"

Step 2: Receiving the Results

Unlike other task types, the ImageToTextTask returns the task execution result directly after createTask, rather than getting it asynchronously through getTaskResult. The response will include the solution to the captcha. Here's an example of the response:

 "errorId": 0,
 "errorCode": "",
 "errorDescription": "",
 "status": "ready",
 "solution": {
 "text": "captcha_solution"
 "taskId": "task_id",


Solving image captchas can be a daunting task, especially when dealing with a large number of them. However, with CapSolver, the process becomes swift and efficient. By following the steps outlined above, you can easily solve image captchas and ensure your automated tasks run smoothly.
