Literature review map in one call. Give a seed paper (DOI, arXiv id, OpenAlex id, or PMID) or a topic query and get one structured result: the seed's references, its cited-by list (most-cited first), and semantically related work, deduplicated into one uniform table with title, authors, year, venue, DOI, and citation count. Collapses search, citation lookup, and related-paper discovery into a single call. Keyless.
