Tools

Six tools for working with bioRxiv and medRxiv preprint data:

Tool

Description

biorxiv_get_preprint

Fetch full metadata, abstract, revision history, and journal crosswalk for one or more preprints by DOI

biorxiv_list_recent

List preprints posted or updated within a date interval, with optional server and category filters

biorxiv_search_preprints

Search preprints by keyword and/or author via EuropePMC for relevance ranking, enriched with bioRxiv/medRxiv metadata

biorxiv_get_published_version

Resolve a preprint DOI to its journal publication record (journal DOI, name, published date)

biorxiv_get_fulltext

Retrieve a preprint's full text as best-effort Markdown extracted from its rendered HTML article page

biorxiv_list_categories

List valid subject category strings for bioRxiv and medRxiv

biorxiv_get_preprint

Fetch preprint metadata by DOI — all revisions in one call.

Batch fetch up to 10 DOIs in a single request

Each DOI returns the full revision history in collection[] — one API call per DOI, no enumeration loop

Includes title, authors, abstract, category, license, JATS XML full-text link (jatsxml), and published journal DOI when the preprint has been accepted

Scope to biorxiv, medrxiv, or both; when both, each DOI fans out in parallel and partial failures report per-DOI in failed[]

biorxiv_list_recent

Page through preprints in a date interval.

Server-side category filtering via ?category=… — pass a value from biorxiv_list_categories

Fixed page size of 30 (API constraint); advance with integer cursor (0, 30, 60, …)

Response includes total count per server for calculating remaining pages

When server="both", each server paginates independently; response
