What you get

Questions this dataset answers

  • What is the latest Microsoft security update bulletin?
  • Were there any out-of-band Windows security releases this month?
  • Which MSRC bulletins shipped in the last 90 days?

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

About this dataset

Corpus buckets: msrc-newest (20 most recently revised/shipped bulletins by CurrentReleaseDate), msrc-releases (20 most recent bulletin RELEASES by InitialReleaseDate — the Patch-Tuesday/out-of-band timeline), msrc-summary (derived counts: total bulletins, current-year releases, revisions in last 7d, newest bulletin title + age). Source: api.msrc.microsoft.com/cvrf/v2.0/Updates (keyless official Microsoft index, 192 bulletins). Each row carries DocumentTitle (e.g. 'September 2026 Security Updates'), bulletin ID/Alias (e.g. 2026-Sep), initial + current release dates, severity where published, and the canonical CVRF document URL. Cadence honesty: MSRC revises or ships bulletins multiple times per week (probe: 7 index changes in 4 days); guaranteed monthly Patch-Tuesday floor covered by a 240h stale threshold. Freshness verifiable on-chain via anchored corpus fingerprints.

How to buy a query

Query 'latest / newest / just updated' → msrc-newest (revision stream); 'Patch Tuesday / released this month / out-of-band' → msrc-releases (release timeline); 'how many / counts / summary' → msrc-summary. Values update hourly; a CurrentReleaseDate bump re-emits a row (revision = churn), new bulletin IDs appear as new rows.

Freshness

Update cadence
Hourly checks; republished when MSRC ships or revises bulletins (multiple updates/week; monthly Patch Tuesday floor) (seller-claimed)
Observed interval

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.
