https://api.openaire.eu/graph/v3/datasources

Quick start

Get all data sources that are journals:

/v3/datasources?dataSourceTypeName=Journal

Retrieve a single data source by its OpenAIRE id:

/v3/datasources/opendoar____::358aee4cc897452c00244351e4d91f69

Endpoints

• GET /v3/datasources — search data sources using the filter parameters
• GET /v3/datasources/{id} — retrieve a single data source by its OpenAIRE id
