Norsk Luftvern — Data & API

Endpoints

The file is pre-built at deploy time. It reflects the state of all published articles at the moment the site last rebuilt. Typical rebuild lag after a new article is published is under five minutes.

Response schema

The response is a JSON object with two top-level keys: meta and articles.

Code examples

curl

curl -s https://norskluftvern.no/api/articles.json | jq '.meta'

JavaScript — fetch all English articles, newest 10

const res  = await fetch('https://norskluftvern.no/api/articles.json');
const data = await res.json();

const latest = data.articles
  .filter(a => a.lang === 'en')
  .slice(0, 10);

console.log(latest.map(a => a.title));

JavaScript — filter by tag

const res  = await fetch('https://norskluftvern.no/api/articles.json');
const data = await res.json();

const patriotArticles = data.articles
  .filter(a => a.tags.includes('patriot'));

Python — build a category index

import requests
from collections import defaultdict

data = requests.get('https://norskluftvern.no/api/articles.json').json()

by_category = defaultdict(list)
for article in data['articles']:
    by_category[article['category']].append(article)

for cat, articles in sorted(by_category.items()):
    print(f"{cat}: {len(articles)} articles")

Python — export all English articles to CSV

import csv, requests

data = requests.get('https://norskluftvern.no/api/articles.json').json()
en  = [a for a in data['articles'] if a['lang'] == 'en']

with open('norsk-luftvern-en.csv', 'w', newline='') as f:
    writer = csv.DictWriter(f, fieldnames=['slug','title','date','category','tags','url'])
    writer.writeheader()
    for a in en:
        writer.writerow({**a, 'tags': ','.join(a['tags'])})

Usage guidelines

Attribution

When displaying or republishing content derived from this feed, please link back to the original article URL (available as the url field on each record) and credit Norsk Luftvern as the source.

Caching

The JSON file is regenerated on every content deploy. We recommend caching it for one hour on the client side. The meta.generated timestamp lets you detect whether a cached copy is stale.

Stability

All field names listed in the schema above are stable and will not be renamed or removed without a changelog entry. New optional fields may be added without notice — write your parser defensively. The articles array is always sorted newest-first.

No authentication or rate limits

The endpoint is a plain static file served from the same CDN as the rest of the site. There is no API key, no OAuth, and no enforced rate limit. Please apply reasonable polling intervals — polling more often than once per hour provides no benefit given the deploy cadence.
