  Live unauthenticated HTTP probes of https://api.sempra.com on 2026-09-04. Sempra
  publishes no authentication documentation on any public surface, so every statement
  below is read directly off the gateway's own responses. Host ownership is established
  from the DigiCert EV certificate on api.sempra.com — subject O=Sempra Energy,
  L=San Diego, ST=California, C=US, serialNumber 2062548, issuer DigiCert EV RSA CA G2.
api: Sempra Developer Portal APIs
base_url: https://api.sempra.com/v1
gateway: Google Apigee
docs: null
docs_note: >-
  There is no public authentication page. https://developer.sempra.com requires
  registration; its anonymous catalog endpoint
  /portals/api/sites/sempra-prod/liveportal/apis returns HTTP 200 with apiDocs [] and
  apiProducts [], and its header menu is exactly "APIs" and "Log In".
note: >-
  api.sempra.com is an Apigee runtime. A request to "/" returns the Apigee
  messaging.adaptors.http.flow.ApplicationNotFound fault (HTTP 404), meaning no proxy is
  routed there. A proxy IS routed at basepath /v1: every path under /v1 — including
  /v1, /v1/graphql, /v1/token and /v1/openapi.json — returns HTTP 401 with an Apigee
  OAuthV2 fault, while /v2/graphql, /oauth/token, /openapi.json, /swagger.json,
  /api-docs and /docs return the not-routed 404. That contrast is the evidence that /v1
  is a real, live, OAuth-protected API basepath. No token issuance endpoint is
  discoverable anonymously and no scope, grant type or client registration flow is
  published — credentials are obtained by registering on https://developer.sempra.com.

    Scheme list is what the gateway demonstrates, not what a spec declares — Sempra
    publishes no OpenAPI, so nothing here is derived from a contract.

    /.well-known/oauth-authorization-server and /.well-known/oauth-protected-resource
    both return the Apigee not-routed 404 on api.sempra.com; /oauth/token is not routed;
    /v1/token is routed but rejects at the OAuth policy before any grant is processed.
    Grant types and scopes are undocumented publicly, so scopes/ is deliberately not
    written — there is nothing real to put in it.
