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.
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
AEMO, the Australian Energy Market Operator, is the independent system and market operator for Australia's electricity and gas systems — it dispatches and prices the National Electricity Market across Queensland, New South Wales, Victoria, South Australia and Tasmania every five minutes, runs the Wholesale Electricity Market and the Gas Bulletin Board in Western Australia, operates the Victorian gas declared wholesale market and the Gas Supply Hubs, maintains the MSATS metering registry and the national Distributed Energy Resources register, and publishes the Integrated System Plan. It sits at the centre of the value chain: it does not generate, network or retail energy, it clears the market and holds the settlement-grade metering data that every other participant depends on. Under the Consumer Data Right extended to energy, AEMO is the designated SECONDARY data holder and gateway — retailers are the primary data holders, and AEMO serves NMI standing data, distributed energy resource records and up to twenty-four months of interval meter data through mandated Consumer Data Standards endpoints. Its API posture splits cleanly in two, and the split is the whole story: the market-data half is genuinely, radically open — 103 live NEMWeb report directories plus 68 archive directories of dispatch, price, demand, bidding, constraint and settlement data downloadable by anyone with no key, no account and no licence, alongside anonymous JSON endpoints behind the public NEM dashboard; the participant and consumer half is completely closed — a public developer portal at dev.aemo.com.au catalogues 74 APIs and 771 operations that anyone may read, but every one of them requires registration as an AEMO market participant, a Participant ID, MSATS user rights and an AEMO-signed mutual-TLS client certificate, and the OpenAPI documents the portal exports publicly are empty shells that declare zero paths and point at internal hostnames.

The JSON API behind AEMO's public National Electricity Market data dashboard, and the closest thing AEMO operates to an open real-time market API. Confirmed live and fully anonymous on 2026-07-27: GET /aemo/apps/api/report/ELEC_NEM_SUMMARY returned HTTP 200 with five-minute regional records for NSW1, QLD1, SA1, TAS1 and VIC1 — settlement date, spot price and price status, total demand, net interconnector interchange, scheduled and semi-scheduled generation, administered-price and market-suspension flags, per-interconnector flows with export and import limits — plus a full FCAS price set (raise/lower regulation and 1s, 6s, 60s and 5min contingency) and the ten most recent AEMO electricity market notices. POST /aemo/apps/api/report/5MIN with body {"timeScale":["5MIN"]} returned HTTP 200 with a rolling five-minute regional price and demand series. No API key, no account, no licence, no rate-limit challenge. It is also entirely undocumented — AEMO publishes no reference, no schema and no terms for it, so it is recorded here as a verified public endpoint rather than as a supported product.

NEMWeb is AEMO's open bulk-data channel for the National Electricity Market and the single largest genuinely open energy dataset in Australia. It is not a REST API — it is an anonymously browsable HTTP directory tree of zipped CSV reports, refreshed on dispatch, daily and settlement cycles, and it is how the entire Australian energy analytics industry gets its data. Confirmed on 2026-07-27: GET https://nemweb.com.au/Reports/Current/ returned HTTP 200 listing 103 report directories — Dispatch_Reports, DispatchIS_Reports, Dispatch_SCADA, Bidmove_Complete, Billing, Marginal_Loss_Factors, Market_Notice, Medium_Term_PASA_Reports, Next_Day_*, Network, ROOFTOP_PV, TradingIS_Reports and more — and GET /Reports/Archive/ returned HTTP 200 with a further 68 archive directories. A sample file, /Reports/CURRENT/DispatchIS_Reports/PUBLIC_DISPATCHIS_202607252230_0000000529244762.zip, downloaded with HTTP 200 and 18,252 bytes of application/x-zip-compressed with no credential of any kind. The MMS Data Model that describes the CSV schemas is published separately at /Reports/Current/MMSDataModelReport.

The Western Australian equivalent of NEMWeb, covering the Wholesale Electricity Market that AEMO operates separately from the NEM. Confirmed anonymous and live on 2026-07-27: GET https://data.wa.aemo.com.au/public/ returned HTTP 200 with directory listings for market-data, public-data, outages, advisories, infographic and INF, and GET /public/market-data/ returned HTTP 200 exposing capo, dsp, mt-pasa, outages, st-pasa and wemde subdirectories — the WEM Dispatch Engine outputs, short and medium term PASA, demand side programme and capacity data. Like NEMWeb it is an open HTTP file tree rather than a REST API, and like NEMWeb it needs no key, account or licence.
