This is a frozen copy of the agent's agent-card.json as we observed it at the timestamp above. We capture a new snapshot every time the card's content hash changes. Useful for: forensic drift analysis, verifying downstream callers see the right version, reproducing routing decisions made historically.

"name": "Agent Checkup by OpenGlass",
"description": "Checks an A2A agent from the outside and tells you what to fix. Give it an agent-card URL or a domain. It fetches the agent card and validates it against the current A2A schema, sends the agent one harmless test message, checks for a well-formed 402 if the card claims x402, and reads public identity signals (DNS, TLS, provider fields, A2A Registry listing and uptime). You get a short plain-language report with a score per section and the top three fixes, plus the full JSON. Each checkup is recorded on OpenGlass, a neutral witness for agent-to-agent interactions, and the report links to that record so anyone can verify it offline. The agent being checked needs nothing from OpenGlass.",
