  Contract discovery + standards search, 2026-09-06. Dillard's publishes no OpenAPI,
  AsyncAPI, GraphQL, gRPC or WSDL contract at any probed location, so nothing here is
  derived from a spec. The one machine-to-machine standard Dillard's demonstrably
  operates is ANSI ASC X12 EDI, mandated of its suppliers and transacted over the
  OpenText/GXS VAN, with the implementation guide and portal gated at
  https://ebiz.dillards.com/ (first-party host, title "WAS 5.0 Dillards Extranet").
note: >-
  READ THIS BEFORE TRUSTING THE X12 ROW. The Dillard's Vendor Information &
  Implementation Guide — the document that IS the contract — is only served to
  authenticated vendors on the eBiz extranet, so the evidence below is
  trading-partner-directory attestation rather than a first-party machine-readable
  artifact we could fetch and save. It is recorded as a real conformance because
  multiple independent EDI networks publish Dillard's mandatory transaction-set list and
  Dillard's own extranet exists to serve it; it is NOT recorded as a readable contract.
  No OpenAPI/REST, OAuth or OpenID surface was found (see well-known/ probe), so no
  oauth2/oidc/rfc9457/json:api rows are asserted either way.
