What you get

Questions this dataset answers

  • What are the newest crates on crates.io?
  • Which new Rust crates were just published with a repository?
  • Latest new cargo packages in the Rust ecosystem?

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

About this dataset

Tracks the crates.io new-crate firehose two ways: (1) cratewatch-newest — the newest crate registrations on crates.io (Rust package discovery, dependency/supply-chain monitoring), and (2) cratewatch-substantive — the newest crates that ship a repository link and a description (substantive new projects vs name claims). Rows are lean: crate name, version, description, canonical crates.io URL, creation time. Source: crates.io public API sort=new (keyless, ~1,000 new crates/day, items arrive minutes apart). Pipeline is idempotent with content-fingerprint dedupe; 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 Rust crates' or 'new crates on crates.io' for the latest registrations (cratewatch-newest bucket); ask for 'substantive new Rust crates' or 'new Rust projects' for repository+description-backed crates (cratewatch-substantive bucket); 'summary' for corpus stats. New registrations land within minutes of publish; the pipeline republishes hourly.

Freshness

Update cadence
Continuous refresh; republished on new crates.io registrations (hourly pipeline; ~1,000 new crates/day, items 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 2026-10-12/2026-10-12. 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.
