  description: 'Sempra runs a Google Apigee API program. api.sempra.com is the Apigee runtime gateway and developer.sempra.com
    is an Apigee integrated developer portal (Apigee organization "sempra", site id "sempra-prod"). Both hosts present DigiCert
    EV certificates issued to O=Sempra Energy, L=San Diego, ST=California, which is how ownership was established. Re-probed
    2026-09-04: the portal still publishes nothing to anonymous visitors — its own catalog endpoint /portals/api/sites/sempra-prod/liveportal/apis
    returns HTTP 200 with "apiDocs": [] and "apiProducts": [], and its header menu is exactly two items, "APIs" and "Log In".
    No OpenAPI, reference, operation list, scope, plan or rate limit is publicly reachable. Anonymous probing does establish
    a live proxy routed at basepath /v1: every path under it (/v1, /v1/graphql, /v1/token, /v1/openapi.json) returns HTTP
    401 with an Apigee oauth.v2.InvalidAccessToken fault and a WWW-Authenticate Bearer challenge, while /, /v2/graphql, /oauth/token
    and /openapi.json return the Apigee messaging.adaptors.http.flow.ApplicationNotFound not-routed 404. The gateway advertises
    GET, PUT, POST, DELETE, OPTIONS and PATCH through a wildcard CORS policy, so a real read/write surface sits behind the
    OAuth wall — but no operation, schema or scope is published.'

description: Sempra is a San Diego-headquartered North American energy infrastructure holding company and a Fortune 500 constituent,
  operating regulated utilities and energy infrastructure across California, Texas and Mexico. Its businesses include San
  Diego Gas & Electric and Southern California Gas Company in California, an ownership interest in Oncor Electric Delivery
  in Texas, and Sempra Infrastructure, which develops LNG export terminals, natural gas pipelines and renewable generation
  in North America. Sempra operates a Google Apigee API program — an OAuth-protected gateway at api.sempra.com and an integrated
  developer portal at developer.sempra.com — and runs sibling Apigee organizations for its California utilities at developer.sdge.com
  (site sdge-prod) and developer.socalgas.com (site socalgas-prod). None of the three portals publishes an API product, contract,
  reference or price to an unauthenticated visitor, so the entire integration surface sits behind portal registration.

  detail: 'Sempra''s Google Apigee developer portal at developer.sempra.com is publicly reachable, but its own anonymous catalog
    endpoint /portals/api/sites/sempra-prod/liveportal/apis answers HTTP 200 with "apiDocs": [] and "apiProducts": [] and
    its header menu is exactly two items, "APIs" and "Log In" — not one API product, contract or reference is published to
    an unauthenticated visitor, while a live OAuth-protected proxy at https://api.sempra.com/v1 answers every anonymous request
    with an Apigee oauth.v2.InvalidAccessToken 401, so the API is real and callable but only by someone already issued a token
    through that portal.'
