# CaptchaLa Documentation

> Developer documentation for CaptchaLa — smart CAPTCHA, human verification, and content-moderation APIs for web, mobile, and desktop apps. Integrate in ~5 minutes with a drop-in widget and verify tokens server-side.

This site documents how to integrate CaptchaLa: add the CAPTCHA widget to your frontend, then verify the returned token from your backend. CAPTCHA challenge types include slider, click, rotate, 3D click, text, and image. The widget renders natively in 47 languages. A content-moderation API (text and image) is also available.

- Localized docs use a path prefix, e.g. https://docs.captcha.la/ja/quickstart, https://docs.captcha.la/zh-CN/quickstart (locales: en, zh-CN, zh-TW, ja, ms, ko, de, es, fr, id, tr, and more).
- The standard flow: render the widget on the client → receive a one-time token → POST it to your server → verify with your secret key via the API or a server SDK.
