Searches 18 scholarly APIs for papers, preprints, citations, open-access full text, repository records, and journal OA status, and returns results with reproducible provenance. Covers PubMed, PMC, Europe PMC, bioRxiv, medRxiv, arXiv, OpenAlex, Crossref, Semantic Scholar, CORE, Unpaywall, OpenCitations, PubTator3, Zenodo, Figshare, ROR, BioStudies, and DOAJ. Use when searching for papers, citations, DOI/PMID/arXiv lookups, abstracts, full text, open-access PDFs, preprints, citation graphs, author publications, biomedical entity annotations, deposited records (Zenodo, Figshare, BioStudies), institution ROR IDs, or any scholarly literature query. Triggers on mentions of any supported database or requests like "find papers on X", "look up this DOI", "who cites this paper", or "get me the PDF". Search 10 academic paper databases via REST APIs for research papers, preprints, and scholarly articles.

The K-Dense-AI copy is a materially different, more advanced version of the skill than the other two. It covers 18 databases instead of 10, adds a 'retrieval contract' step, mandates the use of bundled Python scripts to avoid parsing traps, includes a section on treating API responses as untrusted data, and documents specific failure modes (e.g., HTTP 200 errors). The other two copies (zLanqing and aipoch) are nearly identical to each other, representing an earlier, simpler version of the skill. Because the K-Dense version contains significant new steps and constraints that the others lack, crowning one would hide a real alternative procedure.
