Returns LD-203 semiannual contribution reports — what registered lobbyists and lobbying firms themselves contribute: FECA campaign contributions, honorary expenses, event/meeting costs, and presidential-library / inaugural-committee donations, each item naming the HONOREE (the covered official who benefited). This is the reverse angle of get_lobbying_filings: filings show who pays lobbyists; LD-203 shows where the lobbyists' own money goes. Coverage: 2008→present (~40K filings/year; roughly half are 'no contributions' certifications, excluded by default — set include_empty=true to see them). Record shape: one record per filing — filer (lobbyist name or registrant firm), filing_year + period (mid_year | year_end), nested contribution_items[] (contribution_type, contributor_name, payee_name, honoree_name, amount, date), flattened honoree_names[] / payee_names[] / contribution_types[], and contributions_total_usd (simple sum of item amounts). Filters: honoree_name is the political join — substring against any item's honoree (e.g., 'schumer'). registrant_name matches the firm; lobbyist_name the individual filer; payee_name the receiving committee. contribution_type exact values: 'feca' (campaign money), 'honorary', 'meeting', 'presidential_library', 'inaugural_committee'. Cross-source: pair with get_fec_contributions (the FEC's view of the same FECA money, itemized ≥$200), get_lobbying_filings (the same registrant's client work), get_member_profile (resolve the honoree to party/state/committees). Pure-publisher posture: filings as posted to the Senate LDA system; contributions_total_usd is arithmetic, not a score.
