Sempra Developer Portal APIs is published by [Sempra Energy](https://apis.io/providers/sempra-energy/) on the [APIs.io](https://apis.io/) network. Tagged areas include Energy, Utilities, Apigee, and Developer Portal.

Sempra Energy runs a Google Apigee API program. api.sempra.com is the Apigee runtime gateway — an unrouted request returns the genuine Apigee messaging.adaptors.http.flow.ApplicationNotFound JSON fault — and developer.sempra.com is an Apigee integrated developer portal (Apigee organization "sempra", site id "sempra-prod") whose home page reads "Sempra Developer Portal — Sign up today and start using Sempra APIs". Both hosts present DigiCert EV certificates issued to O=Sempra Energy, San Diego, California, which is how ownership was established. As of 2026-08-28 the portal publishes NOTHING to anonymous visitors: its own catalog endpoint /portals/api/sites/sempra-prod/liveportal/apis returns HTTP 200 with "apiDocs": [] and "apiProducts": [], and the only header menu items are "APIs" and "Log In". No OpenAPI, reference, operation list, plan or rate limit is publicly reachable — every API product is gated behind portal registration. Anonymous probing does establish that a live proxy is routed at basepath /v1: every path under it (/v1/graphql, /v1/token, /v1/graphql/health) returns HTTP 401 with an Apigee OAuthV2 fault and a WWW-Authenticate Bearer challenge, while /v2/* and /oauth/token return the Apigee "no proxy routed" 404. The gateway advertises GET, PUT, POST, DELETE, OPTIONS and PATCH via a wildcard CORS policy, so there is a real read/write surface behind the OAuth wall — but no operation, schema or scope is published.
