Enmax Authentication

generated: '2026-07-27'
method: probed
source: >-
  Live anonymous probes of the ENMAX surfaces listed in apis.yml, 2026-07-27.
  There is no OpenAPI, Swagger or OIDC discovery document anywhere on any ENMAX
  host, so no securitySchemes could be derived; this profile records what was
  observed on the wire instead.

    All ENMAX Power system-capacity ArcGIS REST feature services on
    services1.arcgis.com/NKgP4VcXUzEyOnmg — the FeatureServer metadata
    documents, the layer resources, and /query.
  verified: >-
    HTTP 200 application/json returned with no Authorization header, no token
    query parameter, no cookie and no API key, on 2026-07-27. Verified against
    Generation_Capacity_Layers_20250219_PUBLIC, Feeder_Load_Capacity_Rev9_20251211
    and ENMAX_Service_Area_for_LAF_Verification.
  cors: >-
    access-control-allow-origin "*", with access-control-allow-headers
    "Content-Type, Authorization, X-Esri-Authorization" — browser clients can
    call these endpoints directly from any origin.
platform_token_service:
  note: >-
    The ArcGIS tenant advertises token-based security for PRIVILEGED operations.
    This is the Esri platform gate, not a gate on the public read layers above,
    which were confirmed to answer without a token. Recorded for completeness —
    ENMAX has published no client id, no registration path and no scopes.

  mechanism: >-
    Session-based web sign-in. Registration at
    https://myaccount.enmax.com/register requires an ENMAX account number and a
    phone number. No API is exposed behind it — ENMAX's own support page states
    the Energy Insights usage view "is view-only within your online account and
    can't be exported at this time."

assessment: >-
  ENMAX operates the rarest authentication posture in the catalog — none at all
  on its only published API surface, and no delegation path whatsoever on the
  customer data it holds. The grid data is open because Esri hosting makes it
  open, not because ENMAX decided to publish an anonymous read API; the customer
  usage data is closed because no regulation compels ENMAX to open it and it
  built no consent surface. There is no OAuth 2.0 authorization endpoint, no
  OpenID Connect discovery, no client registration, no scopes, no API keys and
  no accredited-third-party scheme anywhere in the estate.
