About this dataset

Tracks NEW biomedical research papers as they enter PubMed (~4,000 records/day). Two views: the newest papers indexed (any journal, medicine/life-science) and the subset that is new clinical-trial publications — the evidence layer behind trialwatch's registry feed. Each row carries PMID, title, first author, journal, publication date, publication type and DOI when present. The fingerprint covers bibliographic identity (title/author/journal/pubtype/DOI), so corrected records re-emit updated rows. For medical-research agents, evidence-synthesis pipelines, pharma competitive-intelligence and anyone who needs fresh peer-reviewed literature without an API key. Source is NCBI E-utilities esearch+esummary (keyless, contact-bearing UA); corpus refreshed and republished hourly, anchored on-chain every run for verifiable freshness.

How to buy a query

Query phrases map to buckets: 'new pubmed' / 'biomedical paper' hits pubmed-newest (newest indexed papers); 'clinical trial paper' / 'trial publication' hits pubmed-clinical (new clinical-trial publications); 'journal landscape' hits pubmed-summary (journal distribution). Rows update hourly.

Cadence note
Cadence is seller-stated, not measured; republishing is content-gated, so no new version does not mean the pipeline is dead.

FAQ

Do I need an account?

No. Open a prepaid session, fund it, sign the receipt, and query. The listing page never asks for a login.

What do I receive?

Ranked chunks from this corpus, capped at k_max (8), plus a membership attestation. Document bytes are never listed here.

How do I verify freshness?

Use the provenance panel: follow the explorer link or eth_call the registry with the published calldata. Do not take this page as proof.

What is a chunk?

A chunk is a retrieved passage from the corpus — not a full document. Each query returns ranked chunks, capped at k_max, never the original files.

What is the historical coverage?

This listing covers 2026-10-19/2026-10-19. Version history below shows each published snapshot.

Are there rate limits?

Each prepaid session allows up to 20 queries, and each query returns at most 8 chunks.

Can I get a refund?

Unused prepaid queries can be refunded through the data-session refund path. Completed queries are not reversed.
