Python

import requests

r = requests.get("https://nordicenergypulse.com/api/public/v1/prices/today",
                 params={"area": "SE3", "resolution": "1h"}, timeout=10)
r.raise_for_status()
data = r.json()
best = data["cheapest_windows"][2]  # 3-hour window
print(best["start_local"], best["average_eur_cents_per_kwh_incl_vat"])

JavaScript

const res = await fetch("https://nordicenergypulse.com/api/public/v1/prices/current?area=NO1");
const { current } = await res.json();
console.log(current.local_per_kwh_incl_vat, "NOK/kWh");

Fair use and errors

Send a normal User-Agent header (as any browser, Python or Home Assistant client does) — requests without one, or with an empty one, are refused before reaching the API.
60 valid requests per minute per client, counted across all servers. Rejected requests (400) don't use up this allowance but have their own limit. Over the limit you get HTTP 429 with a Retry-After header.
Give each parameter once — repeating one (e.g. two area values) returns 400 duplicate_parameter. Paths are lowercase; other spellings are redirected.
Responses are cached (current 1 min, today 1–5 min, history 30 min) and send an ETag — polling every 5 minutes is plenty.
Errors are JSON: { "error": { "status", "code", "message" } } — 400 invalid parameter, 404 unknown endpoint, 405 wrong method, 503 source unavailable.
CORS is open, so the API works directly from browser apps. No personal data is collected or stored.
