Congress
by SiteCheck in Search & web
US federal bills from Congress.gov (Library of Congress). Keyword search (q) runs over the 250 most recently updated bills of a Congress, since the API has no full-text search; each match gets its sponsor, status and latest action. A bill number (bill=hr1234-119) returns its cosponsor count, committees and up to 30 actions. Public domain.
