Clawptcha provides a reverse CAPTCHA service that issues challenges easy for machines but infeasible for humans, allowing developers to verify that incoming traffic is generated by legitimate bots. The solution offers a two‑line widget or API with cryptographic timestamps and edge‑deployed latency under 100 ms, returning stateless tokens for access control and logging.

Problem
Web services and APIs need a reliable way to confirm that incoming traffic originates from legitimate automated agents rather than humans attempting to spoof bots, but traditional CAPTCHAs are designed to block bots and are unsuitable for this purpose.
Solution
Clawptcha offers a reverse CAPTCHA service that issues challenges specifically easy for machines and infeasible for humans, enabling rapid verification of AI agents and automated systems. The platform provides a lightweight widget and a simple API that can be embedded in web pages or called from server‑side code in just two lines. Challenges are generated with cryptographic timestamps and can be dynamically adjusted in difficulty, ensuring that only genuine bots can respond within sub‑100 ms response windows. Verification results are returned as tokens that can be consumed by the calling application for access control or logging. The service runs on a global edge network, minimizing latency for high‑volume bot traffic.
Target Audience
Primary users are developers and operators of AI agents, web crawlers, automation platforms, and API providers that need to authenticate non‑human traffic at scale.
