§ OD · Open data Everything the Pis collect

Pick an endpoint.
Make something good with it.

Every live figure on this site comes from a handful of JSON endpoints on api.ronnyhullegie.nl. You're welcome to fetch them. Research, your own visualisation, school project. Just drop me a line and share what you build.

§ OD · 02 Quick try
In the terminal
curl https://api.ronnyhullegie.nl/api/weer/current
In the browser

Paste the URL into your address bar. The JSON shows up directly. Firefox and Chrome format it neatly. For your own project: fetch() in JavaScript, requests.get() in Python.

§ OD · 03 All endpoints

Base URL is always https://api.ronnyhullegie.nl/api. Each endpoint is GET, returns JSON, and includes a generated_at field so you know how fresh the data is.
