Free, forever
Check a measurement yourself
Checking what has been measured, and re-checking the signature on it, is free and stays free. There are no plans, tiers, accounts or prices. A grade is never sold, and we issue no marks of approval.
Look up your MCP server or agent
Paste an MCP server, A2A agent or x402 endpoint URL. Council of AI's lookup lists every signed capsule it holds about it and lets you re-check each one in your browser. Free, no account.
Opens on councilof.ai. The lookup shows states and proofs, not a grade.
Re-check a signed record

From an agent
The same checks are open to agents with no key: MCP at https://councilof.ai/mcp (tools such as verify_card and verify_capsule) and A2A at https://councilof.ai/api/a2a. See councilof.ai/connect.
Nothing measured yet?
If the record you need does not exist, order a run. Until then the honest answer is UNMEASURED.
