Capy Inc.

Capy Inc. operates Lemin Captcha, a gamified bot-prevention and CAPTCHA service that replaces traditional image-selection challenges with playful, brandable puzzle games. Lemin protects websites and apps from automated attacks such as account takeover and credential stuffing while improving the human experience: the company reports puzzles are solved in roughly five seconds (versus eighteen for legacy CAPTCHAs) with far lower abandonment. Developers embed a client-side widget (available as first-party React, Angular, and Vue components on npm), then verify the visitor's encrypted answer server-side against the Lemin verification API using their account private key. Capy Inc. is a 500 Global portfolio company.

Capy Inc. publishes 1 API on the APIs.io network: Verification API. Tagged areas include Company, Security, CAPTCHA, Bot Detection, and Bot Prevention.

Capy Inc.’s developer surface includes documentation, API reference, getting-started guide, support, pricing, signup flow, authentication, and 19 more developer resources.
