Overview
Luchtmeetnet API provides real-time and predicted air quality measurements from the official Dutch national air quality monitoring network (RIVM). It is completely free with no authentication required, covering pollutants like NO2, PM10, PM2.5, and ozone across hundreds of stations in the Netherlands. Developers can fetch station data, component measurements, and LKI (air quality index) values with simple GET requests.
Beginner Tip
No API key is needed — just browse the available stations first using the /stations endpoint, then use a station number to fetch current measurements. The API returns metric-based pollution data, so check the Luchtmeetnet docs for the list of supported component codes like "NO2" or "PM25".

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.
const url = "https://api.luchtmeetnet.nl/open_api/stations?organisation_id=1";
const response = await fetch(url);
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data); What Can You Build?

How This API Fails
We deliberately sent this API a broken request and recorded exactly what came back on 2026-08-10. Knowing the shape of an error before you hit it makes error handling much easier to write.
