Quickstart: business electricity rates API

1. Request rates for a location

No sign-up or API key is needed. Ask for a postcode:

curl "https://api.termina.com/v1/rates?postcode=2000"

import requests

r = requests.get("https://api.termina.com/v1/rates", params={"postcode": "2000"})
data = r.json()
print(data["summary"]["cheapest"])

const res = await fetch("https://api.termina.com/v1/rates?postcode=2000");
const data = await res.json();
console.log(data.summary.cheapest);

2. Read the answer from `summary`

summary is written to be read directly:

"summary": {
  "usage_kwh": 10000,
  "checked_at": "2026-10-16",
  "cheapest": {
    "offer_source": "termina_buying_group",
    "network": "ausgrid",
    "annual_cost_inc_gst": 2862,
    "vs_benchmark_pct": -36.7,
    "benchmark_abbreviation": "DMO"
  },
  "cheapest_public": {
    "retailer": "Future x Power",
    "plan_name": "SME Cable Small Biz 25",
    "annual_cost_inc_gst": 3413,
    "vs_benchmark_pct": -24.5
  },
  "coverage": { "plans_compared": 353, "plans_public": 311, "retailers_public": 22 }
}

In words: for a business using 10,000 kWh a year on the Ausgrid network, the cheapest rate is

2,862 a year incl. GST through the Termina buying group, 36.7% less than the Default Market Offer. The cheapest public plan is Future x Power's at

3,413.

summary.cheapest always matches the first plan in plans on page 1, so the answer and the table never disagree.

3. Re-cost at the business’s own usage

10,000 kWh a year is the default, the AER’s small business reference usage. If you know the business’s usage, pass it, and every plan and the benchmark are re-costed:

curl "https://api.termina.com/v1/rates?postcode=2000&usage_kwh=25000"

For time-of-use and demand tariffs you can also pass peak_share, shoulder_share and max_demand_kw. See How rates are costed.

4. Page through every plan

Plans come 10 at a time. Pass pagination.next_cursor as cursor for the next page, until pagination.has_more is false:

curl "https://api.termina.com/v1/rates?postcode=2000&cursor=eyJvIjoxMCwicCI6e30sImQiOltdfQ"
