Sempra Developer Portal APIs is published by [Sempra](https://apis.io/providers/sempra/) on the [APIs.io](https://apis.io/) network. Tagged areas include Energy, Utilities, Apigee, and Developer Portal. The published artifact set on APIs.io includes authentication docs.

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.
