Citation graph for a scholarly work via OpenAlex.

Citation graph for a scholarly work via OpenAlex. Pass id as a DOI (10.xxxx/…, doi.org URL) or an OpenAlex work id (W…). Returns the work's total citation count + reference count, and a paginated list of either the works that CITE it (view=citing, default — sort=recent for newest-first or sort=citations for most-cited-first) or the works it REFERENCES (view=referenced). Each listed work gives DOI, title, year, venue, authors, and its own citation count. Fresh citation data lands after any training cutoff. Complements papers.search (finding papers) with graph traversal (following citations).
