Tools & capabilities
Crossref tools 3
search_worksSearch academic papers, books, and datasets via Crossref. For "search works titled X" / finding a SPECIFIC paper by its title, pass `title` (title-scoped — ranks the exact paper first). Beyond keyword search you can SORT by citation count or publication date and FILTER by date range, work type, author, and JOURNAL (`journal` = a journal name like "Progress in Materials Science" or an ISSN; results are restricted to that journal only) — e.g. "most-cited papers on transformers" (sort=citations), "papers on LLMs since 2024" (from_date=2024-01-01), "recent journal articles by an author". Returns titles, authors, journal, DOIs, citation counts, and dates.get_workGet full metadata for a publication by DOI (e.g., "10.1038/nature12373"). Returns title, authors, abstract, journal, publisher, citations, and subjects.get_journalGet the 5 most recent works from a journal by ISSN (e.g., "2041-1723"). Returns titles, authors, DOIs, and publication dates.
