generated: '2026-09-19' method: probed source: >- Live GET probes of the named /.well-known/* path list on liquidagent.ai, www.liquidagent.ai, api.liquidagent.ai and docs.liquidagent.ai on 2026-09-19. Every row is a request that was actually issued; every status is the one returned. No MCP host exists to probe (see mcp/liquidagent-ai-mcp.yml). summary: hosts_probed: 4 paths_probed: 45 documents_served: 6 hit_hosts: [api.liquidagent.ai] note: >- Every served document sits on the API host. api.liquidagent.ai serves an A2A agent card at BOTH the canonical /.well-known/agent-card.json and the legacy /.well-known/agent.json (byte-identical, 3,429 bytes), an x402 v2 discovery manifest at /.well-known/x402 (byte-identical to /openapi.json - the provider serves its OpenAPI as the x402 manifest), an x402 resource catalog at /.well-known/x402-resources, and an ERC-8004 registration file at /.well-known/erc8004.json. It also serves an agents.txt at the root. None of the OAuth/OIDC, security.txt, api-catalog, ai-plugin, UCP/ACP/AAuth or APIs.json paths exist on any host. The apex 307s every path to www., and www. returns a real 404 for every /.well-known/* path. docs.liquidagent.ai is a dead Vercel deployment (DEPLOYMENT_NOT_FOUND) behind a Let's Encrypt certificate that expired 2026-03-07. path_echo_control: passed path_echo_control_note: >- GET https://api.liquidagent.ai/.well-known/liquidagent-ai-negative-control-9f2c7a1e.json returned 404 with the API's JSON NOT_FOUND envelope, so the 200s on this host are real documents, not a catch-all. hosts: - host: api.liquidagent.ai role: API host (OpenAPI servers[] and apis[].baseURL); the only host serving any discovery document documents: - path: /.well-known/security.txt status: 404 - path: /.well-known/openid-configuration status: 404 - path: /.well-known/oauth-authorization-server status: 404 - path: /.well-known/oauth-protected-resource status: 404 - path: /.well-known/api-catalog status: 404 - path: /.well-known/api-catalog.json status: 404 - path: /.well-known/ai-plugin.json status: 404 - path: /.well-known/ucp.json status: 404 - path: /.well-known/acp.json status: 404 - path: /.well-known/aauth-resource.json status: 404 - path: /.well-known/apis.json status: 404 - path: /apis.json status: 404 - path: /apis.yml status: 404 - path: /.well-known/agent-card.json status: 200 content_type: application/json; charset=utf-8 file: ../a2a/liquidagent-ai-agent-card.json standard: A2A Agent Card (graded in a2a/liquidagent-ai-a2a.yml) - path: /.well-known/agent.json status: 200 content_type: application/json; charset=utf-8 file: ../a2a/liquidagent-ai-agent-card.json standard: A2A Agent Card, pre-0.3 legacy path note: Byte-identical to /.well-known/agent-card.json; not saved twice. - path: /.well-known/x402 status: 200 content_type: application/json; charset=utf-8 file: liquidagent-ai-x402.json standard: x402 discovery manifest note: >- Byte-identical to https://api.liquidagent.ai/openapi.json (26,719 bytes).
