Crossref Search Skill
Search the metadata that publishers deposit with Crossref when they register DOIs. No API key needed.
Overview
Crossref is the largest DOI registration agency. Its REST API (https://api.crossref.org) returns JSON for about 188 million works: journal articles, books, book chapters, reference entries, dissertations, and conference papers. Many records include an abstract, the reference list, and a citation count.
It is metadata only. It does not search full text, and it does not give access to paywalled articles.
