Resolve scholarly identifiers (DOI including shortDOI aliases, PMID, PMCID, ISBN, arXiv, ISSN, ADS bibcode, WHO IRIS URL) into formatted citations (10,000+ CSL styles) and bibliography exports (BibTeX, RIS, EndNote, CSV…), and check retraction, open-access, and citation-fabrication status — from the terminal via the `scholar` CLI. Wraps the public REST API; needs Node ≥20 but no API key for the free tier. Use when the user wants to look up, cite, export, or verify a reference by DOI, PMID, PMCID, ISBN, arXiv ID, ISSN, ADS bibcode, or WHO IRIS URL from the terminal — including retraction, open-access, and fabricated-citation checks, or a whole-bibliography audit of a .bib/.ris/CSL-JSON file.
