AEMO NEM Data Dashboard API
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.
