source: live probes of the 2X website host and the Knownwell API/MCP hosts
note: >-
  Probed three hosts. The corporate website (2x.com, formerly 2x.marketing) serves no
  /.well-known/ documents at all — every path 404s, and the WordPress theme answers those
  404s with a full HTML page rather than a bare status, so none of them is a document. The
  real /.well-known/ surface belongs to the Knownwell MCP server at mcp.knownwell.com,
  which publishes proper OAuth 2.0 discovery: RFC 8414 authorization-server metadata and
  RFC 9728 protected-resource metadata. Knownwell was acquired by 2X on 2026-06-10, which
  is why a 2X artifact records a knownwell.com host.
