Tools

• biorxiv_get_fulltext ~888 tokens
  Retrieve a preprint's full text as best-effort Markdown, extracted from its rendered HTML article page. Reads the latest version unless one is requested (the version input, or a vN suffix on the DOI), confirms it via the details API, then fetches and extracts the body — abstract, sections, inline ci
• biorxiv_get_preprint ~587 tokens
  Fetch full metadata, the abstract, all revision history, JATS XML full-text links, and published-journal DOI for one or more preprints by DOI. Each DOI returns all revisions in one response, with the abstract on the latest revision only — the API keeps one abstract per preprint. Each call looks up t
• biorxiv_get_published_version ~584 tokens
  Resolve a DOI to its preprint-to-journal crosswalk record — preprint DOI, journal DOI, journal name, published date, and corresponding author details — from either side: a preprint DOI (10.1101/ or 10.64898/) finds the journal article it was published as, and any other DOI is read as a journal artic
• biorxiv_list_categories ~153 tokens
  List valid subject category strings for bioRxiv and medRxiv — the categories the listing API actually filters on. Use these strings as the `category` filter in biorxiv_list_recent to narrow results to a specific field; case, and "_" or "-" in place of a space, do not matter there. Run this tool befo
• biorxiv_list_published_versions ~1066 tokens
  List preprints that appeared as journal articles within a journal publication-date interval, each with its journal DOI, journal name, publication date, and preprint metadata — the same record biorxiv_get_published_version returns for one DOI. The dates filter on journal publication, not preprint pos
• biorxiv_list_recent ~906 tokens
  List preprints posted or revised within a date interval, optionally scoped to one server or a subject category. Returns 30 preprints per page (fixed by the API); pass `cursor` as an integer offset (0, 30, 60, …) to step through additional pages. Abstracts are omitted by default to keep the page smal
• biorxiv_search_preprints ~756 tokens
  Search preprints by keyword and/or author using EuropePMC for relevance ranking, then enrich matching DOIs with full bioRxiv/medRxiv metadata. Provide a keyword query, an author name, or both — author maps to an EuropePMC AUTH: field query and is ANDed with the keyword query. Covers both servers by
