AWS WAF / bCaptcha image recognition

AwsClassification recognizes AWS WAF CAPTCHA 3x3 image challenges and bCaptchaClassification recognizes bCaptcha 3x3 image challenges: send the whole image and the question, and get back which cells to click; your code clicks them in the browser. They do not return a token. They are synchronous and cost 8 points (¥0.008) per request.

Without code, use the browser extension.
