What makes Image CAPTCHA different

Where the Image CAPTCHA parameters come from

The body parameter contains the image payload. If drawn on a canvas, toDataURL() can serialize the canvas before removing the data-URL prefix. The case_sensitive, charset, and math parameters constrain interpretation only when required by the source challenge.

bodyRequired
The challenge payload itself. Its media type follows this page's task: image data for visual tasks and audio data for the audio task.
case_sensitiveOptional
Whether letter case must be preserved when interpreting the returned text.
charsetOptional
The allowed character set for image recognition when the source challenge restricts its alphabet.
mathOptional
Whether an image-text task should interpret the recognized content as a mathematical expression.
