Arxiv

Arxiv Search

Search arXiv papers by query with category and sort filters. Returns paper metadata including title, authors, abstract, categories, and links.

Arxiv Get Metadata

Get full metadata for one or more arXiv papers by ID. Use when you have known IDs from citations, prior search results, or memory.

Arxiv Read Paper

Fetch the full text of an arXiv paper. Tries arxiv.org/html first, falls back to ar5iv.labs.arxiv.org, and falls back again to text extracted from the PDF when neither has an HTML render — check the source field to know which one answered. Page through long papers with start and max_characters, or pass max_characters null to get the entire body in one call.

Arxiv List Categories

List arXiv category codes and names. Useful for discovering valid category filters for arxiv_search. Lists subject classes only; arxiv_search also accepts a bare archive code (the part before the dot, e.g. "astro-ph" or "cs") to search a whole archive at once.
