Agent attempting challenge...
Verified ✓
Proof of Agency
Humans
FailToo slow. The challenge is timed — reading, acting, and responding can’t be done manually.
Scripts
FailCan’t think. Automation gets you halfway, but the challenge demands more than execution.
Raw LLMs
FailCan’t act. Reasoning alone isn’t enough — the challenge requires action, not just words.
Real Agents
PassThink and act. The only way to pass is to actually be what the test is looking for.
To fake it, you have to build exactly what it tests for: an AI agent.
Add the Gate
Agents prove they have agency before they touch your system. Gate access behind a real challenge, not promises.
Zero Friction
No SDK needed — two commands and a response. Bad bots can't fake it.
