Luxembourg Open Data Scraper

Luxembourg Open Data Scraper

Scrape Luxembourg open data datasets by search term, tag, or organization, up to a million per run. Every dataset comes with its title, description, publisher, update date, and resource links. No API key required. Export to CSV, JSON, Excel, or XML.

Luxembourg publishes thousands of public datasets on data.public.lu, but browsing the portal page by page is slow and manual filtering is limited. This Actor reads the platform's public API directly, letting you search by keyword, tag, or organization and collect matching dataset metadata in one structured table. It is built for analysts, journalists, and developers who need a clean export of what data exists on a topic.

Who uses it	What they scrape data.public.lu for
Data analysts	Discover which transport or budget datasets the government has published this quarter
Journalists	Find environment and health datasets for an investigation on Luxembourg's public spending
Open data advocates	Monitor new dataset releases across all Luxembourg public bodies in one export
Developers	Build an automated catalog of Luxembourg open data resources for a civic app

What it does

This Actor collects dataset metadata from data.public.lu by search query, tag, or organization, and returns each dataset as a flat row.

• 🔍 Full-text search: find datasets by keyword across titles and descriptions, e.g. "transport", "budget", "environnement".
• 🏷️ Tag filter: narrow results to a specific tag slug like "mobility" or "santé".
• 🏛️ Organization filter: limit datasets to one publisher by its slug or 24-character identifier.
• 📄 Paginated collection: control page size up to 100 and collect up to 1,000,000 datasets per run.

Results export to CSV, JSON, Excel, or XML, or straight from the API.

What you can do with data.public.lu data

🚌 Monitor transport data releases.

A mobility analyst searches for "transport" and the tag "mobility" each month to see which new GTFS or traffic datasets the Administration des transports published.

📊 Audit public budget transparency.

A civic tech group collects all datasets tagged "budget" across every Luxembourg ministry to check which financial data is available and which is missing.

🌱 Track environment and climate datasets.

An environmental researcher filters by the tag "environnement" and exports the full list of air quality, water, and waste datasets for a policy report.

🏥 Find health and social datasets.

A public health journalist searches for "santé" and collects dataset metadata from the Ministry of Health to identify data sources for a story on hospital capacity.

Configure the run

Drive the Actor with a search query, a tag, an organization slug, or leave all filters empty to list the most recent datasets. Filters are applied at the API level so only matching datasets count toward your limit. The Input tab lists every parameter.

A first run with the defaults:

{
  "pageSize": 20,
  "maxItems": 10
}

A larger pull:

{
  "pageSize": 20,
  "maxItems": 200
}

Then prompt it in plain language to run the scraper and read back the results.

Troubleshooting

Why am I getting no results?

Check that your search query, tag, or organization slug exactly matches a value on data.public.lu. Try leaving all filters empty first to confirm the API is reachable, then add filters one by one.

The Actor returns fewer datasets than my maxItems setting.

The platform only returns datasets that match your filters. If fewer datasets exist for that query, tag, or organization, the Actor will stop early. Try broadening your search or removing a filter.

I get an error about an invalid organization.

Make sure you are using the exact slug from the organization's page URL on data.public.lu, or the 24-character ID. Slugs are case-sensitive.

The run is slow with a high maxItems.

The Actor respects the platform's API rate limits. Increase the pageSize to fetch more datasets per request and reduce the total number of API calls.

Some datasets have no resource links.

Some datasets on data.public.lu are metadata-only or link to external sites. The Actor returns whatever the API provides; missing resources are not an error.

FAQ

Question	Answer
Do I need an API key or a data.public.lu account?	No. The Actor reads the public API of data.public.lu, which is open and requires no authentication.
What exactly does the Actor return?	It returns metadata for each dataset: title, description, the publishing organization, the last update date, and a list of attached resources with their URLs and formats.
Can I download the actual data files?	The Actor collects the resource links (CSV, JSON, XLSX, etc.) for each dataset. You can use those URLs to download the files separately or feed them into another Actor.
How do I search in French or German?	Enter your search term in the query field in French (e.g. "transports"), German ("Verkehr"), or English. The platform's full-text index covers all three languages.
What is a tag slug and where do I find it?	A tag slug is the short identifier used in the URL on data.public.lu, like "mobility" or "environnement". Open a tag page on the portal and copy the last part of the URL.
How do I filter by a specific ministry or organization?	Use the organization field with the slug (e.g. "cfl-mobility") or the 24-character ID. The Actor resolves slugs automatically.
What happens if I leave all filters empty?	The Actor returns the most recently created or updated datasets on the platform, up to your maxItems limit.
How many datasets can I collect in one run?	You can set maxItems up to 1,000,000. The platform itself has thousands of datasets, so a high limit will collect everything available.
Can I schedule this Actor to run weekly?	Yes. Set up a schedule in Apify with your chosen filters, and the Actor will collect any new or updated datasets that match.
What export formats are supported?	You can export the results to CSV, JSON, Excel, or XML from the Apify dataset tab.
