description: 'W. W. Grainger, Inc. (NYSE: GWW) is a Fortune 500 broad-line distributor of maintenance, repair and operating
  (MRO) products serving businesses and institutions across North America, Japan and the United Kingdom through roughly 331
  branches, 34 distribution centers and its digital channels. Its system-to-system commerce runs through eProcurement rather
  than a public developer program: PunchOut catalogs into Ariba, Coupa, Jaggaer, SAP, Oracle and GHX, ANSI ASC X12 4010 EDI
  for purchase orders, acknowledgments, ship notices and invoices, and the KeepStock inventory-management program. Grainger
  operates an API gateway at api.grainger.com, but its Swagger surface answers anonymous callers with an ACCESS DENIED page
  requiring the Grainger corporate network, and integration credentials are issued only by a Grainger account representative,
  so no public API contract or reference is available to evaluate.'

x-coverage:
  state: gated
  reason: customer-only-docs
  detail: Grainger runs a live API gateway at api.grainger.com whose only routed documentation path, /swagger.json, answers
    anonymous callers with HTTP 503 "ACCESS DENIED - Log onto the Grainger Network ... through a secure VPN connection", and
    its eProcurement PunchOut and X12 4010 EDI credentials are issued only by a Grainger account representative over a stated
    4-6 week onboarding, so no contract or reference exists outside an active customer agreement.
