Academic paper search, scientific literature, citation analysis, arXiv & semantic related-work.
Daily (~4am PT): OpenAlex (primary, keyless, rich metadata + citations), arXiv (CS/physics/math/bio preprints), PubMed (biomed). Abstracts are embedded with fastembed (bge-small) for similar_papers (pgvector cosine). citation_graph and author_profile resolve live from OpenAlex. Semantic Scholar is an optional enhancement (TLDR/relevance via S2_API_KEY; keyless S2 rate-limits hard).
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
