Find federal candidates by name, state, office, party, or cycle. Retrieve a specific candidate by FEC ID with financial totals. Candidate IDs start with H (House), S (Senate), or P (President) followed by exactly eight letters or digits.

Find political committees (campaign, PAC, Super PAC, party) by name, type, candidate affiliation, or state. Retrieve a specific committee by FEC ID. Committee IDs start with C followed by exactly eight digits (e.g., C00358796).

Get pre-aggregated committee financial totals — receipts, disbursements, cash on hand, debts, and the itemized/unitemized breakdown — without paginating Schedule A. Use mode "single" (the default) with a committee_id for one committee's totals, one row per two-year cycle it has filed. Use mode "by_entity_type" to rank or screen every committee of one type (presidential, pac, party, pac-party, house-senate, ie-only) by state, designation, or a receipts/disbursements threshold.

Search itemized individual contributions (Schedule A) or get aggregate breakdowns by size, state, employer, or occupation. Use to answer "who is funding this committee?" Itemized mode requires a committee_id. Aggregate by_size/by_state can use candidate_id instead.

Search itemized committee spending (Schedule B) or get aggregate breakdowns by purpose or recipient. All modes require a committee_id. Use to answer "what is this committee spending money on?" or "who is receiving payments from this committee?"

Search independent expenditures (Schedule E) — outside spending supporting or opposing federal candidates. Covers Super PACs, party committees, and other groups. Use itemized mode for individual expenditure records, or by_candidate for aggregated totals per candidate; by_candidate needs either a candidate_id or a full race scope (candidate_office alone for President, plus candidate_office_state for Senate, plus candidate_office_district as well for House).

Search coordinated party expenditures (Schedule F) — spending a party committee makes on behalf of a candidate it supports, in coordination with that campaign. Distinct from independent expenditures (openfec_search_expenditures), which cannot be coordinated with the candidate, and from direct contributions: coordinated expenditures carry their own statutory limits and can run into tens of millions per party in a presidential cycle. Scope with a spending committee_id, a benefiting candidate_id, or a cycle; unscoped queries span all years.

Search FEC filings and reports by committee, candidate, form type, or date range. Covers financial reports (F3/F3P/F3X), statements of candidacy (F2), organizational filings (F1), 24-hour IE notices (F24), and amendments.

Look up federal election races and candidate financial summaries. Find who's running in a race with fundraising totals, or get an aggregate race summary.

Search FEC legal documents: advisory opinions, enforcement cases (MURs), alternative dispute resolutions, administrative fines, and statutes. The citation, penalty, respondent, ao_number, and case_number filters each apply to only some document types; with type omitted, the search returns only the types every one of them applies to. Each response is held to 100,000 bytes: when a page would exceed it, whole results are held back and nextFromHit gives the from_hit that continues each document type.

Fetch one FEC legal document — advisory opinion, MUR, ADR, administrative fine, or statute — by its type and number. openfec_search_legal replaces each result's documents and dispositions arrays with a count and category summary and cuts every commission vote down to a date and a 200-character action; this returns the record as upstream sends it, whole when it fits the 100,000-byte response budget. A larger record returns its scalar fields and the arrays that fit, with the rest listed in withheld; page through one by re-calling with array and offset. doc_type is the plural form of the document_type discriminator on a search result (advisory_opinion becomes advisory_opinions, mur becomes murs, adr becomes adrs, admin_fine becomes admin_fines, statute becomes statutes), and no is that result's no field — every document type carries it, and advisory opinions repeat it as ao_no.

Look up FEC calendar events, filing deadlines, and election dates. Use to find upcoming filing windows for a committee, locate when a federal election occurred, or scope FEC events by date range and category.
