How this service works
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.
Output
A paginated list of lobbying filing records, each containing: filing type code, year, period, reported income or expenses in USD, registrant details (id, name, state), client details (id, name, description, state), a list of lobbying issues with codes and descriptions, lobbyist count, a URL to the official Senate LDA document, and a posted timestamp.
Example use cases
Example prompt
“Pull up Senate LDA lobbying filings where Brownstein Farber is the registrant for the year 2023, second_quarter period — show me the first 10 results including reported income, client names, and lobbying issues covered.”
Technical details
Endpoint
GEThttps://2s.io/api/gov/lobbying-filingsWhen to prefer
Use this endpoint when you need structured, filterable access to US federal Senate LDA lobbying disclosure data — specifically to search by firm, client, individual lobbyist, year, quarter, or filing type. Prefer this over scraping senate.gov directly or using general web search when you need clean structured data with income figures, issue codes, and document links in a single API response.
Side effects
- No results returned when registrant/client/lobbyist name string does not match any filing — try broader partial-match terms
- Invalid period enum value returns a 400 or empty response — must use exactly: first_quarter, second_quarter, third_quarter, fourth_quarter, mid_year, or year_end
- Year out of range (before 1999 or after 2030) rejected by schema validation
- pageSize exceeding 25 rejected — maximum is 25 per request
- Upstream Senate LDA data source unavailable causes service errors
