DataGov Search Datasets

Search the US federal open data catalog (Data.gov) for datasets from agencies like EPA, CDC, Census Bureau, NIH, USDA, NOAA, and more. Data.gov uses the CKAN API and indexes over 300,000 federal datasets. Returns dataset titles, descriptions, organizations, download resource URLs, tags, and last-modified dates. Use organization filter (e.g. 'epa-gov', 'cdc-gov', 'usda-gov', 'nih-gov', 'census-gov', 'noaa-gov') to narrow results to a specific agency.
