VouchSafe API

The service provides and alternative to CAPTCHA for validating form submissions and preventing abusive submissions by scripts or bots. Instead of entering distorted characters, the service presents a series of images and allows a human user to use a mouse to draw a line connecting related images or to circle an unrelated item. An "adaptive AI" modifies the service's behavior over time based on aggregated user actions. API methods support generation of an image set, along with JavaScript that adds the challenge and handles user input. Methods also return validation results reporting the user's success or failure at completing the challenge.
