API Quickstart

Your first request​

All Graph API endpoints share the base URL https://api.openaire.eu/graph/. No account is needed: public requests work without authentication, within the rate limits for unauthenticated use.

This request uses filter-based queries to find publications from 2023 onwards, returning three records with only their identifier, title and publication date:

curl "https://api.openaire.eu/graph/v4/research-products?filter=type:publication,from_publication_year:2023&select=id,mainTitle,publicationDate&page_size=3"

The response carries a header with the total match count and paging details, followed by the results:

{
  "header": { "numFound": 43527166, "page": 1, "pageSize": 3, ... },
  "results": [
    { "id": "06cdd3ff4700::3c8734759ca685b966b1d737c37daeed",
      "mainTitle": "The fundamental structures of prehistoric societies",
      "publicationDate": "2026-01-16" },
    ...
  ]
}
