OpenAlex API

A free, high-throughput REST API providing programmatic access to a massive, fully open graph of global scholarly research.

The OpenAlex API serves as a modern, open-source alternative to proprietary databases like Scopus and Web of Science. It indexes over 470 million scholarly works (including articles, books, and datasets) and links them directly to authors, institutions, funders, and publishers. Developers can query the API using standard REST endpoints to filter, sort, and group data by specific fields (such as DOIs, ORCIDs, or RORs). The service is free to use with a registered API key, delivering up to 100,000 daily credits for automated research tools, citation analysis, and institutional tracking.
