# Welcome!

## Welcome to ClearCaptcha API

Welcome to the ClearCaptcha API! Here you will find all the documentation you need to bypass various Captcha and Anti-crawler services. All api data are millisecond-level real-time responses, and will not poll for data like other platforms that bypass Captcha (eg. 2captcha, anit-captcha...)

## Want to jump right in?

The following APIs for bypassing Captcha and anti-crawling services have been opened, jump to the quick start document and start making your first request
