This is not our API. This repository is an independent, third-party profile of a company's publicly available API surface, maintained by API Evangelist. API Evangelist does not operate, host, resell, or support this company's APIs, and is not affiliated with or endorsed by the company unless stated on the profile.
Where the information came from. Everything here is assembled from material a member of the public can reach with a browser and no credentials — the company's own website, developer portal and documentation, the specifications it publishes for public use (OpenAPI, AsyncAPI, JSON Schema,
apis.json,llms.txtand similar), its public repositories, and its public status, pricing and changelog pages. Nothing here is obtained by breaching a system, defeating an access control, or using credentials of any kind.The rating is an independent assessment. The Kin Score and Agent Readiness rating are independently calculated scores of a company's public API artifacts, produced by API Evangelist against a published rubric. They are not certifications, endorsements, security assessments, or audits, and they score published artifacts — not the quality, safety, or security of the software.
Corrections, re-scores, and removal are free. No partnership, contract, or purchase is required, and you do not need to justify the request.
- Something wrong? Open an issue on this repository, or email info@apievangelist.com.
- Published something new? Ask for a re-score and we will re-run the rating.
- Want the listing taken down? Say so and we will honor it. The profile is reduced to your company name, a factual description, and a link to your own site, and the company is recorded as unrated — never scored zero for having asked.
Response times. Acknowledgement within one business day; removal or restriction within two business days; corrections and re-scores within five business days.
Not from the company, and here with a question? You are welcome here — we would rather be the front line and point you the right way than have a good report go nowhere. What this repository can answer is narrow, though, so it is worth knowing who you are actually looking for:
- A question about how the API works, an account, billing, or a bug in the service — that is the company's own support, not us. We profile this API; we do not operate it and cannot see your account.
- A bug in an open-source project we only catalog — file it on that project's own repository. This has happened with a real and correct bug report that reached us instead of the people who could fix it, which helped nobody.
- Anything about this listing itself — the description, the tags, the rating, a missing or wrong artifact — is ours. Open an issue here.
- Not sure, or something general about API Evangelist or APIs.io — open an issue on the APIs.io Inbox and we will route it.
This repository contains no software, and we will never ask you to download anything. There is no build, release, installer, or binary here — only text and machine-readable API descriptions, so there is nothing here that can be "corrupt" or need "repairing". Any issue, comment, or email claiming otherwise and offering a download link is not from us and is hostile. Do not follow the link; it is a lure. Report it to GitHub and, if you like, tell us at info@apievangelist.com so we can take it down.
On a security or compliance team? Email info@apievangelist.com with security in the subject line and you will get a person, not a form. We will tell you exactly which public URLs this profile was built from so your team can see the same surface we did, and we will take the listing down on request while you work through it.
Full detail: Where this data comes from
Simply Energy is the former brand of the Australian electricity and gas retailer that now trades as ENGIE, operated by IPower Pty Ltd (ACN 111 267 228) and IPower 2 Pty Ltd (ABN 24 070 374 293) trading as ENGIE (ABN 67 269 241 237), together with Simply Energy Solutions Pty Ltd. The business carried the Simply Energy name for seventeen years before rebranding to ENGIE in April 2024, and supplies more than 700,000 residential and business accounts across Victoria, South Australia, New South Wales, Queensland and Western Australia. It sits on the retail tier of the National Electricity Market value chain, buying wholesale energy and billing end customers, rather than in generation, transmission or distribution. Its API posture is entirely a product of statutory mandate, and in this case the mandate is genuinely implemented rather than merely claimed. The company is a designated Consumer Data Right energy data holder (data holder provider number DH002028) and is listed on the live CDR Register under the ENGIE brand. Its unauthenticated CDR Generic Plans endpoint, hosted for it by the Australian Energy Regulator's Energy Made Easy service, returns 2,452 real ENGIE tariff plans conforming to the Consumer Data Standards energy schemas, and its own registered public base URI serves the Consumer Data Standards discovery endpoints with correct x-v version negotiation. Everything else is closed. Customer usage, billing, service point and DER data are available only to ACCC accredited data recipients with explicit consumer consent, there is no developer portal, no self-serve API keys, no published OpenID Connect discovery document, and no open grid, market or system data of any kind.

The evidence: the public CDR Register lists brand ENGIE (ABN 67269241237, publicBaseUri https://public.cdr.engie.com.au) among 84 energy data holder brands — and lists no brand named "Simply Energy". That registered base URI answers GET /cds-au/v1/discovery/status and /cds-au/v1/discovery/outages with HTTP 200 at x-v: 1 and rejects higher versions with urn:au-cds:error:cds-all:Header/UnsupportedVersion. The mandated generic tariff data answers with 2,452 real ENGIE plans. See review.yml for every URL probed and every status code returned, including the control test that proves the tariff payload — not the status code — is what establishes the implementation.
Public, unauthenticated Consumer Data Right Generic Tariff Data for the Simply Energy / ENGIE retail brand, conforming to the Data Standards Body Consumer Data Standards energy schemas. Confirmed live on 2026-07-27 — GET /energy/plans returns HTTP 200 with x-v: 1 and meta.totalRecords 2452 ENGIE electricity and gas plans (MARKET and STANDING) across Ausgrid, Endeavour, Essential Energy, Energex, SA Power Networks, Jemena and AGN distribution zones. GET /energy/plans/{planId} returns HTTP 200 at x-v: 3. The endpoint is hosted on behalf of the retailer by the Australian Energy Regulator's Energy Made Easy service; it is not self-hosted.

The Consumer Data Standards Common Discovery API served from the brand's own registered CDR Public Base URI. Confirmed live on 2026-07-27 — GET /discovery/status returns HTTP 200 at x-v: 1 with status OK, and GET /discovery/outages returns HTTP 200 at x-v: 1 with an empty outages array. Both correctly reject x-v: 2 and above with urn:au-cds:error:cds-all:Header/UnsupportedVersion. This host does not serve /energy/plans — it returns an nginx HTTP 404 — which matches the behaviour of AGL, Alinta and Origin Energy and reflects the CDR energy design in which generic tariff data is centralised at the Australian Energy Regulator rather than held by each retailer.

The mandated Consumer Data Right consumer data sharing surface — energy accounts, balances, billing, invoices, concessions, payment schedules, electricity service points, usage and distributed energy resources — conforming to the shared Consumer Data Standards energy contract. Not anonymously verifiable and deliberately listed without a base URL: the CDR InfoSec and resource base URIs for a data holder are published only through the authenticated portion of the CDR Register and are reachable only by an ACCC accredited data recipient presenting a client certificate. Access requires ACCC accreditation, OAuth2 / OpenID Connect under the CDR FAPI profile, mutual TLS, and explicit consumer consent. Recorded here as designated and documented, not as an endpoint confirmed by API Evangelist.
