Campaign finance & influence

Campaign Contributions

Returns FEC Schedule A contribution data — money flowing INTO federal committees — in aggregated form: totals by employer, state, candidate, committee, or cycle, plus a top-donor leaderboard. Individual contributions are served as aggregates only (no per-record name search, no contact info), the presentation the FEC's sale-or-use rule (11 CFR 104.15) explicitly permits.

What it returns

Three modes, one endpoint:

Aggregate totals (group_by) — one row per group: group_by, cycle, key, label, total_amount, contribution_count, plus candidate/committee context (candidate_id, committee_id, party, office, individual_itemized_contributions, disbursements, cash_on_hand) and source_url provenance. Served live from the FEC's own aggregate endpoints, so totals reconcile with fec.gov.
Donor leaderboard (leaderboard=true) — top individual donors for one bounded scope: rank, contributor_name, contributor_employer, total_amount, contribution_count, with scope + itemization-floor + complete metadata. No addresses, city, or ZIP — aggregated totals only.
Per-record rows (non-individual only) (entity_type) — itemized PAC / party / committee / organization contributions with full filing provenance (sub_id, receipt_type, report_type, pdf_url, source_url…). Individual (IND) rows are never returned per-record.

Filters

group_by	Aggregate mode: employer \| state \| candidate \| committee \| cycle. employer/state require recipient_committee_id + cycle (the FEC computes those per committee); cycle requires candidate_id or recipient_committee_id.
leaderboard	Leaderboard mode: top individual donors (name + employer + summed total). Requires cycle + exactly one scope: recipient_committee_id \| candidate_id \| contributor_state \| contributor_employer.
recipient_committee_id	FEC committee ID (e.g., 'C00401224'). Aggregate/leaderboard scope, or per-record filter. Use the FEC Candidates dataset to find a candidate's principal committee.
candidate_id	FEC candidate ID (e.g., 'S8GA00180'). Aggregate/leaderboard scope, or per-record filter.
contributor_state	2-letter state code. Leaderboard scope (top donors from a state) or per-record filter.
contributor_employer	Employer name. Leaderboard scope only — top donors reporting this employer.
entity_type	Per-record mode — NON-INDIVIDUAL types only: COM, CCM, PAC, PTY, CAN, ORG. Individual (IND) rows are served aggregated only.
sub_id	Per-record direct lookup by FEC sub_id (returned only for non-individual rows).
cycle	Election cycle year (2-year transaction period). Common values: 2026, 2024, 2022.
min_amount	Leaderboard: itemization floor for aggregated rows (default 1000; 200 = FEC itemization floor). Per-record: inclusive lower bound on amount.
max_amount	Per-record mode: inclusive upper bound on amount.
since / until	Per-record mode: bounds on contribution_receipt_date (YYYY-MM-DD).
exclude_memos	Per-record mode: when true (DEFAULT), filters memoed_subtotal duplicates that double-count dollars. Leaderboards always exclude them.
sort_by / sort_order	Per-record mode sort. Default: contribution_receipt_date desc.
limit	Max rows / donors to return. Default 50 (leaderboard 100), max 500.
