Public APIs

Exploring Public APIs in Belgium with JavaScript

As a developer, you know the importance of having access to reliable data sources. Luckily, Belgium has an abundance of public APIs that provide access to various datasets. In this article, we will explore one such API - https://data.gov.be/.

What is https://data.gov.be/?

https://data.gov.be/ is a portal that provides access to various public datasets in Belgium. From traffic data to weather information, you can find a plethora of datasets on this platform. As a developer, you can use this data for research, analysis, and creating innovative applications.

How to Access https://data.gov.be/ APIs?

To access the APIs offered by https://data.gov.be/, you will need an API key. You can register for an API key on the website for free. Once you have the API key, you can make API calls to the datasets.

The syntax for accessing the APIs is as follows:

https://api.\"dataset\".data.gov.be/v1/data/?apikey=\"API_KEY\"&q=

Replace dataset with the name of the dataset you want to access and API_KEY with your API key. You can also include search parameters in the q parameter.

Example API Calls in JavaScript

Here are a few examples of API calls to get you started:

Example 1: Retrieving Traffic Data

const apiKey = "YOUR_API_KEY";
const url = `https://api.mobilitydata.be/v1/trafficflownodes/?apikey=${apiKey}`;

fetch(url)
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error(error));

This code retrieves traffic flow data from the Mobility Data API. Replace YOUR_API_KEY with your API key.

Example 2: Retrieving Environmental Data

const apiKey = "YOUR_API_KEY";
const url = `https://api.luchtmeetnet.be/v1/airquality/?apikey=${apiKey}&location=&parameter=PM10`;

fetch(url)
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error(error));

This code retrieves PM10 air quality data from the Luchtmeetnet API. Replace YOUR_API_KEY with your API key.

Example 3: Retrieving Weather Data

const apiKey = "YOUR_API_KEY";
const url = `https://api.meteo.be/v1/forecast/location/?apikey=${apiKey}&location=nivelles`;

fetch(url)
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error(error));

This code retrieves weather forecast data for Nivelles from the Meteo Belgium API. Replace YOUR_API_KEY with your API key.

Conclusion

https://data.gov.be/ offers a wealth of public datasets that you can use to build innovative applications. With the examples provided in this article, you can start exploring the various datasets and create applications that leverage them. Happy coding!

Open Government, Indonesia

Indonesian Government Open Data.CKAN is a tool for making open data websites. (Think of a content management system like WordPress - but for data, instead of pages and blog posts.) It helps you manage and publish collections of data. It is used by national and local governments, research institutions, and other organizations who collect a lot of data. Once your data is published, users can use its faceted search features to browse and find the data they need, and preview it using maps, graphs and tables - whether they are developers, journalists, researchers, NGOs, citizens, or even your own staff. For CKAN purposes, data is published in units called “datasets”. A dataset is a parcel of data - for example, it could be the crime statistics for a region, the spending figures for a government department, or temperature readings from various weather stations. When users search for data, the search results they see will be individual datasets.
