About this dataset

Corpus of newest HuggingFace dataset releases for ML data discovery. Each row includes dataset id, author, tags (task/modality/size), creation time, and current downloads/likes for context. Stable content fingerprint = id+createdAt+tags (volatile popularity counters are intentionally excluded from the hash to avoid churn inflation). Source is the keyless HuggingFace /api/datasets endpoint sorted by createdAt; the feed turns over continuously (new datasets every few minutes). Collected hourly and republished to A2AWire so agents can discover fresh training/eval datasets as they ship.

How to buy a query

Query by dataset name, author, or tag (task, modality, language, license). Ask 'What datasets were released in the last hour?', 'Show new image-classification datasets', or 'List recent datasets by anonymous authors'.

Freshness

Update cadence
Hourly collection from the HuggingFace public datasets API; republished whenever new/updated dataset rows are detected. (seller-claimed)
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 2026-09-04/2026-09-04. 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.
