GET metastore/schemas/dataset/items/{datasetId}

cms.gov:cms-provider-data-api

Summary: Get Dataset Metadata
Operation ID: getDataset
Auth: none

Returns detailed metadata for a specific dataset identified by its unique ID. Unlike the bulk list endpoint, this returns a single dataset's complete metadata record including title, description, contact information, update schedule, keywords, themes, and download URLs. Call this when you know the dataset ID (from browsing the catalog) and want to understand what data it contains, when it was last updated, and where to download the full dataset as CSV.

Original spec description

Returns detailed metadata for a specific dataset by its identifier.

Usage Tips

- Returns 404 if the dataset ID doesn't exist - The `distribution` array contains direct download URLs - usually CSV files - Check `modified` and `nextUpdateDate` to understand data freshness - `describedBy` links to PDF data dictionaries that explain field meanings
