Disambiguate a researcher and return their profile: works count, citation count, h-index, institutions with ROR, top concepts and top works. Give an orcid for a resolved profile, or a name for ranked candidates. Distinct people are never merged.
Citation graph of a paper: the works it references (outgoing) and the works that cite it (incoming), each as normalized records, plus the Semantic Scholar influential-citation count. Give a doi, arxiv, pmid, openalex_id or title. Ideal for literature review and prior-art mapping.
Resolve one research paper and fuse its metadata across OpenAlex, Crossref, Unpaywall and Semantic Scholar into a single cited JSON. Give a doi, arxiv, pmid, pmcid, openalex_id or title and get canonical metadata, authors with ORCID and affiliations, venue, citation counts, an open-access PDF link and a full id crosswalk.
