OpenAlex
OpenAlex is a free and open catalog of scholarly research, with a REST API for querying connected records such as works, authors, sources, institutions, and topics. API users can search, filter, sort, group, page through results, select fields, and retrieve individual entities. The complete database snapshot can be downloaded from Amazon S3 without an AWS account, and the data is released under the CC0 public-domain license. An official command-line tool supports bulk downloads with parallel transfers, checkpoints, rate limiting, retries, and resume. Full-text access provides PDFs and machine-readable TEI XML; each file download costs $0.01. Website exports include CSV, RIS, and TXT, while VOSviewer connects through the API. OpenAlex also offers Unpaywall's legacy-format open-access API, including a browser extension and integrations with SFX, EBSCO Discovery Service, and 360 Link. Its coverage includes journal articles, conference papers, books, chapters, datasets, dissertations, and preprints. OpenAlex is operated by a US 501(c)(3) nonprofit, and its code is open source.
