Hugging Face Dataset Viewer

Use this skill to execute read-only Dataset Viewer API calls for dataset exploration and extraction.

Core workflow

1. Optionally validate dataset availability with /is-valid.
2. Resolve config + split with /splits.
3. Preview with /first-rows.
4. Paginate content with /rows using offset and length (max 100).
5. Use /search for text matching and /filter for row predicates.
6. Retrieve parquet links via /parquet and totals/metadata via /size and /statistics.

Defaults

• Base URL: https://datasets-server.huggingface.co
• Default API method: GET
• Query params should be URL-encoded.
• offset is 0-based.
• length max is usually 100 for row-like endpoints.
• Gated/private datasets require Authorization: Bearer <HF_TOKEN>.

Dataset Viewer

• Validate dataset: /is-valid?dataset=<namespace/repo>
• List subsets and splits: /splits?dataset=<namespace/repo>
• Preview first rows: /first-rows?dataset=<namespace/repo>&config=<config>&split=<split>
• Paginate rows: /rows?dataset=<namespace/repo>&config=<config>&split=<split>&offset=<int>&length=<int>
• Search text: /search?dataset=<namespace/repo>&config=<config>&split=<split>&query=<text>&offset=<int>&length=<int>
• Filter with predicates: /filter?dataset=<namespace/repo>&config=<config>&split=<split>&where=<predicate>&orderby=<sort>&offset=<int>&length=<int>
• List parquet shards: /parquet?dataset=<namespace/repo>
• Get size totals: /size?dataset=<namespace/repo>
• Get column statistics: /statistics?dataset=<namespace/repo>&config=<config>&split=<split>
• Get Croissant metadata (if available): /croissant?dataset=<namespace/repo>

Pagination pattern:
