Scholarly literature search in every discipline (Crossref
Scholarly literature search in every discipline (Crossref: articles, preprints, books, proceedings, datasets), filtered by author, years, type or abstract, sorted by relevance, date or citations; a DOI returns that work. Each work has DOI, title, authors with ORCID, venue, date, citation counts, licence, open-access links, the abstract where CC-licensed for commercial use, and retraction, correction and concern notices. For citation checks and literature reviews. No matches: not charged.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
