Attention!

Using proxy servers is not required for this task.

The request must contain a single image in base64 format.

Request parameters

IMPORTANT: obtain the base64 image directly before creating the task to avoid errors during solving (see section How to get base64).

imagesBase64<array>required

Base64-encoded image (wrapped in an array, without the data:image/png;base64, prefix).

---

Task (inside metadata)<string>required

Task name: "MathSum"

How to get Base64

Images on pages can be represented either as a URL or already encoded in Base64 format. To find the required value, right-click the captcha image, select Inspect, and carefully examine the Elements section or network requests — there you can find either the image URL or the encoded content.

1. Open your website where the captcha is displayed in the browser.
2. Right-click the captcha element and select Inspect.
