See this example : 

if (slingRequest.getParameter("numericbox1614079614831").length() >= 5) {
GuideCaptchaValidatorProvider apiProvider = sling.getService(GuideCaptchaValidatorProvider.class);
String formPath = slingRequest.getResource().getPath();
String captchaData = slingRequest.getParameter(GuideConstants.GUIDE_CAPTCHA_DATA);
if (!apiProvider.validateCAPTCHA(formPath, captchaData).isCaptchaValid()){
response.setStatus(400);
return;
}
}
