Watch biology's preprints
arrive, pinned to DOI.
bioRxiv and medRxiv are where new biology and medicine surface first. biorxiv_recent lists a date window of preprints and biorxiv_fetch pulls one by DOI — resolving to the journal-published version when the preprint has since been accepted.
What the instrument does
bioRxiv (biology) and medRxiv (clinical/health) are the life-science preprint servers. Their API is date-window based — there is no keyword search — so you browse what posted, newest first, and filter by category.
On the console, biorxiv_recent returns a window's preprints (optionally filtered to a category like genomics), and biorxiv_fetch retrieves a specific DOI, following through to the published article when one exists.

How Perslis integrates bioRxiv & medRxiv
The runtime is honest about the API's shape. bioRxiv has no keyword search, so the instrument does not pretend to: it returns exactly the date window asked for, filters category client-side, and states plainly when a window is empty rather than inventing preprints to fill it.
When a preprint has been published, biorxiv_fetch follows the DOI to the version of record — so a citation points at the peer-reviewed paper, not a superseded draft, the moment one exists.
Ask
One question at the console — no per-service query language, no tab-hopping.
Route
Lois calls this instrument alongside the others and gathers what returns.
Pin
Every field keeps its source: database, accession, URL. A result that cannot name its source is refused by construction.
Admit
The PEEL gate decides what enters the lab record. Reported values stay verbatim; unsupported claims stay out.
A real, source-pinned result
Pulled live from the service and pinned to its identifier — the same contract every answer on the console is held to.

Why route bioRxiv through one console
Preprint feed, callable
An agent watches the newest biology by date window without scraping the site.
Preprint to version of record
A DOI follows through to the published paper the moment the preprint is accepted.
Honest about empty
An empty window returns as zero — the runtime never fabricates preprints to fill a gap.
Instruments bioRxiv talks to
Preprints join the published record. bioRxiv answers next to arXiv and the indexes that track acceptance.
