Graph API V4 (BETA)

Beta

The V4 API is currently in beta. Endpoints and parameters may change before the stable release.

The V4 API introduces a unified filter syntax that replaces the 30+ individual query parameters of previous versions with a small set of orthogonal meta-parameters.

Instead of separate parameters like type, authorOrcid, etc., V4 collapses all filters into a single filter parameter with a compact field:value syntax (e.g. filter=type:publication,from_publication_year:2023).

You can access the Swagger documentation at Swagger UI.
