I Built a Free Compliance Auditor for AI Agent APIs — 32 Checks in 5 Seconds

AI agents are starting to transact with each other. They call APIs, send payments, and make decisions autonomously. But here's the problem: how does one agent know if another agent's API is trustworthy? There's no standard way to verify if an API s payment protocols, has proper security headers, publishes identity information, or follows regulatory requirements. Until now, the only option was manual review. What I built Probe runs 32 automated compliance checks on any API endpoint in under 5 seconds. No signup, no API key, no cost.
