Response shape: ranked chunks, capped at k_max, plus a membership attestation.

About this dataset

Tracks the npm publish firehose: npm-newest carries the newest package updates (release events for dependency monitoring), npm-unscoped highlights unscoped package names (rare, discovery-relevant — most modern packages are @scoped), and npm-summary carries corpus stats. The npm updates feed is event-driven: each item is a package publish with its event timestamp and current README excerpt. Rows are intentionally lean: package name, canonical npmjs.com URL, publish time, publisher, README excerpt. Source: registry.npmjs.org (keyless official feed, updates continuously). Pipeline is idempotent with content-fingerprint dedupe (package + URL + publish event time); corpus freshness is anchored on-chain each hourly run so buyers can verify data age without trusting us.

How to buy a query

Ask about 'newest npm releases' or a package name for recent publish events (npm-newest bucket); ask about 'unscoped packages' for non-@scoped name discoveries (npm-unscoped bucket); 'summary' for corpus stats. Publish events land within minutes of publish; the pipeline republishes hourly.

Freshness

Update cadence
Continuous refresh; republished on new npm publish events (hourly pipeline; feed items arrive minutes apart) (seller-claimed)
Observed interval
~1h 1m
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.
