Classification support
Query interface, directly submit the whole sentence of the problem, if you encounter a new category, please contact customer service to add.
Because the HCaptcha is updated so frequently, the document no longer lists all the categories, and you just upload the questions you get from the web page.
If it is a new category, we will support it within 3 working days
If it's an existing category and it's just a different way of asking the question, we'll update it every day.
