data.gov / Search U.S. government datasets

Searches the data.gov catalog of U.S. federal, state and local government open datasets by keywords: for each dataset its title, description, publisher and organization, keywords, themes, access level, the data.gov slug, and its DCAT record with distributions (download and API links, formats) and the publisher's contact point. Optional filters: one keyword tag, one organization slug. Pages with per_page (1 to 20, default 10) and the after cursor from the previous answer. A search with no match answers an empty list, a miss. Catalog metadata is U.S. government work; each dataset keeps the licence its publisher states (the record's dcat.license or rights).
