  Live GET probes of the named /.well-known/* path list plus /apis.json and /apis.yml on agentcheck.care,
  www.agentcheck.care and agentcheck.clinic, 2026-09-19. Every row below is a request that was issued;
  every status is the one returned.

    One real well-known document: the A2A Agent Card at /.well-known/agent-card.json, served on the apex
    and on www (agentcheck.clinic 301s to the apex copy). Every other path in the closed list — security.txt,
    openid-configuration, oauth-authorization-server, oauth-protected-resource, api-catalog, ai-plugin.json,
    ucp.json, acp.json, aauth-resource.json, apis.json, /apis.json, /apis.yml — returns a genuine JSON 404
    ({"detail":"Not Found"}, application/json, 22 bytes) from the FastAPI origin. There is no SPA shell
    false positive on this host. No MCP host exists to probe (mcp.agentcheck.care does not resolve; POST
    tools/list to /mcp and /api/mcp 404), and the agent card names no authorization server, so the host set
    is the three domains the company itself names.
