**Canonical:** https://apis.io/apis/university-of-helsinki/datakatalogi-rest/  
**Provider:** University of Helsinki — https://apis.io/providers/university-of-helsinki/  
**Base URL:** https://datakatalogi.helsinki.fi/server/api  
**Documentation:** https://datakatalogi.helsinki.fi/

HY Data Catalogue DSpace REST API is one of 26 APIs that [University of Helsinki](https://apis.io/providers/university-of-helsinki/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Research Data, Data Catalog, DSpace, Open Data, and DataCite. The published artifact set on APIs.io includes an API reference.

A SECOND, separate DSpace deployment — datakatalogi.helsinki.fi, running DSpace 9.0 with dspaceName "HyDatacatalogue" — cataloguing research DATA rather than publications. New: its OAI earliest datestamp is 2026-08-12. Registered as a Haka SAML service provider. It is easy to miss because Helda absorbs all the attention, and it was absent from this profile until the 2026-08-30 re-run.
