Overview

The University of Oslo Open Data API provides free access to information about courses, lecture videos, and academic content from one of Norway's largest universities. No authentication is needed, making it straightforward to explore structured educational data. It is particularly useful for developers building academic tools or studying how universities expose their course catalogs.

💡

Beginner Tip

Start by exploring the catalog at https://data.uio.no to understand what datasets are available before writing code—the portal provides dataset previews and download options alongside API access.

Common Errors & Troubleshooting

404 on dataset endpoint Using an incorrect or outdated dataset ID in the request URL.
✓ Fetch the package list first via /api/3/action/package_list to get valid dataset IDs, then use those in subsequent calls.
Response not in expected format The API uses CKAN's API format, which wraps results in a {success, result} envelope.
✓ Access the actual data via response.result rather than treating the top-level object as the dataset.
Slow or timeout on large datasets Some lecture video datasets are very large and take time to retrieve.
✓ Use the rows and start parameters to paginate through results in smaller batches.
