Api Endpoint

2s

Search US federal lobbying disclosures (Senate LDA filings) — who lobbies for whom, on what issues, for how much. Filter by registrant (lobbying firm name), client (organization being represented), lobbyist (individual name), year, period (first_quarter|second_quarter|third_quarter|fourth_quarter|mid_year|year_end), and type (e.g. RR=registration, Q1-Q4=quarterly reports). Each filing: type, year/period, reported income or expenses (USD), registrant + client (id/name/description/state), lobbying issues (code + description), lobbyist count, official document URL, posted timestamp. Money-in-politics, journalism, and policy-intelligence staple. Public federal data.
