Graph API

The OpenAIRE Graph API provides a comprehensive way for developers to explore the OpenAIRE Graph, a vast interconnected dataset that aggregates metadata from a wide range of scholarly resources. The Graph API offers endpoints for accessing and querying this interconnected dataset, enabling users to retrieve detailed information on research products, data sources, organizations, projects, and persons.

Base URL and Swagger documentation

The base URL of the Graph API is:

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

You can access the Swagger documentation at Swagger UI.

Each entity is exposed under its own /v3 path:

Entity	Search endpoint	Single entity
Research products	GET /v3/research-products	GET /v3/research-products/{id}
Organizations	GET /v3/organizations	GET /v3/organizations/{id}
Data sources	GET /v3/datasources	GET /v3/datasources/{id}
Projects	GET /v3/projects	GET /v3/projects/{id}
Persons	GET /v3/persons	GET /v3/persons/{id}

Notes

Please note that the Graph API:

• Offset-based paging works with a limit of 10,000 results per query. For complete dataset access, consider using cursor-based paging or downloading the full OpenAIRE Graph dataset.
• adheres to the terms of use of the OpenAIRE public APIs - certain (rate limit) restrictions apply.
