AI Tool / Agent Challenge / Verification
A reverse CAPTCHA site that gives short timed tasks for LLMs and agents, with an MCP endpoint, machine-readable docs, challenge submission, certificates, and a leaderboard.
The page shows a live AI-adjacent product with a specific purpose: challenge agents on short tasks and verify results. It exposes multiple usable surfaces for builders, including /llms.txt, an MCP endpoint, challenge tools, certificate verification, and a leaderboard. The snapshot provides enough evidence to list it as a public AI tool.
The snapshot does not show example challenges, how hard the tasks are, or what kinds of agents it is meant to test beyond a general LLM-friendly task flow. It also does not show broader documentation, pricing, or whether the service is meant for production use versus a novelty demo.
