FunCaptcha image recognition

FunCaptchaClassification recognizes FunCaptcha (Arkose Labs) image puzzles: send the puzzle image and the English question, and get back which image to pick; your code clicks it in the browser. It does not return a token. It is synchronous and costs 3 points (¥0.003) per request.

Tip

For a token instead of click positions, use FunCaptcha. Without code, use the browser extension.

Request parameters

Field	Type	Required	Description
type	string	Yes	Task type; see "Task types and pricing" on this page
image	string	Yes	Base64-encoded challenge image without the data: prefix
question	string	Yes	The question text in English (e.g. Pick the image that is the correct way up); supported questions are listed on this page

• image contains only the puzzle images (usually a 6-tile grid), without the title or buttons above it. Make sure screenshots are complete; a missing part hurts accuracy. Vertical 6-tile layouts can be uploaded as they are.
• question is the full English question exactly as shown, with correct capitalization; don’t translate it yourself. If the page is in another language, switch the captcha to English first. The server picks the puzzle type from the question, so it must be exact.
