University of Groningen Research Portal (Pure) REST API is one of 6 APIs that [University of Groningen](https://apis.io/providers/university-of-groningen/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include CRIS, Pure, Elsevier, Research, and Tenant. The published artifact set on APIs.io includes API documentation and authentication docs.

The Elsevier Pure web service deployed on the University's CRIS host. Probed 2026-08-30: pure.rug.nl/ws/api redirects to /ws/api/documentation/index.html, whose rel=canonical is https://api.elsevierpure.com/ws/api/documentation/index.html — the contract, the version numbering, the documentation and the api-key scheme are all Elsevier's, and the archived source specification carried info.contact.email pure-support@elsevier.com. The University is the tenant and the data is the University's research record. Recorded here as a relationship; Elsevier's specification is deliberately not saved under this institution, and the thirty-seven per-tag splits of it that this repo carried until 2026-08-30 have been removed.
