method: probed
source: live GET probes on every host the record knows (apex, www, docs host aux., API/A2A host api.aux.) on 2026-09-19
note: >-
  Real hits: the A2A agent card (canonical path on api.aux + aux + www; legacy path on aux + www), the ARD manifest
  (/.well-known/ard.json, also mirrored at /.well-known/ai-catalog.json) and the AUX production manifest
  (/.well-known/aux.json) on the docs host, and the receipt-signing JWKS on the API host. No security.txt,
  openid-configuration, oauth-authorization-server, oauth-protected-resource, api-catalog, ai-plugin.json, mcp.json
  or aauth-resource.json on any host. There is no MCP host (mcp.prdictionedge.ai and mcp.aux.prdictionedge.ai do not
  resolve) and no discovery document names an authorization server, so no third host was probed. The apex
  prdictionedge.ai 307s every path to www.prdictionedge.ai; a 404 on the Next.js hosts is an HTML error page (20,293
  bytes, same body as a random control path) and a 404 on the API host is a JSON body ({"error":"not_found"}), so
  every 200 recorded below is a served document, not a catch-all shell.
hosts:
- host: prdictionedge.ai
  note: Apex; every /.well-known/* path returns 307 to the same path on www.prdictionedge.ai.
