Captcha API

Free, fast and reliable Captcha API


Captcha API designed and developed by Akshit Kumar (akshit.me) is a free to use public grade API for developers to protect their websites and applications from fraud and abuse. Read the documentation

The V2 of the API uses advanced Artificial Intelligence to place elements in the image to prevent model creation for any OCRs that may be able to solve the captcha programmatically. The AI decides on the characters to use, the placement of those characters, placement of circles, formation of circles, color of captcha letters and the background gradient.
