Forge Tools crossref_lookup

crossref_lookup read

scidex.forge.crossref_lookup

DOI → citation metadata. Hits Crossref's /works/{DOI} endpoint and returns title, authors, year, journal, ISSN, publisher, type, citation count, and an open-access URL when registered. Complements PubMed for papers PubMed doesn't index (CS venues, datasets, book chapters, preprints with DOIs).
