CORE

API

Free API for accessing global Open Access research papers

Overview

The CORE API provides RESTful access to millions of Open Access research papers worldwide. Key endpoints include paper search (with filters for subject, author, publication date), metadata retrieval (title, abstract, authors, citations), full-text access (where permitted), and institution-specific paper listings. Responses are JSON-formatted. Use cases include building academic research tools, automating literature reviews, integrating scientific content into educational platforms, data mining for citation analysis, and supporting open science initiatives. It offers both unauthenticated (basic) and authenticated (higher rate limits) access tiers.

Example Integration (JavaScript)

script.js JS


fetch('https://core.ac.uk/services#api')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
