  title: AEMC Energy Rules Search API
  version: '2026-07-27'
  description: 'Machine-readable description of the undocumented JSON API that serves the Australian Energy Market Commission''s Energy Rules application at https://energy-rules.aemc.gov.au. It exposes the consolidated, versioned text of the National Electricity Rules (NER), National Gas Rules (NGR) and National Energy Retail Rules (NERR) — the rule versions and their PDF/DOCX artefacts, the table of contents, every chapter/part/division/rule/clause node, the full-text search index and the complete defined-terms glossary.


    AEMC publishes NO OpenAPI, no developer portal and no API documentation for this surface. This document is DERIVED, not harvested. Every path below is a literal route string taken from AEMC''s own shipped production JavaScript bundle (https://de4oj9etm9d7w.cloudfront.net/b8470902-3d28-4902-8883-2c59d10e7818/js/app.js), and each one was probed live and anonymously on 2026-07-27 with the observed HTTP status recorded in `x-evidence`. Response schemas are derived ONLY from responses actually observed on those probes — no field, parameter or status code is invented.


    ACCESS: entirely anonymous. No API key, no OAuth, no cookie and no CSRF token was required for any read endpoint probed; responses carry `x-ratelimit-limit: 1000` and `x-ratelimit-remaining`, served through AWS API Gateway (`apigw-requestid`) in front of a Laravel application (Laravel API Resource `data`/`links`/`meta` envelope, Laravel-style pagination).


    NOT MODELLED: the production bundle also contains an administrative, token-gated approval route of the form `/api/v1/{type}/{version}/approve/{token}` used by the editorial preview workflow. It is a state-changing endpoint, it was deliberately NOT probed, and it is deliberately not modelled here. The `previewToken` query parameter that several read endpoints accept belongs to the same editorial preview workflow and is not usable anonymously.


    STATUS: this is an undocumented internal API of a public website, not a product AEMC offers or supports. There is no published terms-of-use, rate-limit policy, SLA, versioning policy or contact for it. Treat it as subject to change without notice, and report inaccuracies rather than treating this document as an authoritative contract.'
