The rule of thumb

Every dataset is public government or public-domain disclosure data, legal to collect and use for personal or research purposes. Redistributing it commercially is a separate question with real constraints:

Every other dataset (SEC EDGAR, USAspending, USPTO, LDA.gov, Senate/House disclosures, Wikimedia) is unrestricted public-domain U.S. government data. None of the above blocks personal use, local research, or the API as shipped.
