US federal campaign finance from the FEC (openFEC). Two modes: pass name to search candidates (returns FEC candidate id, party, office, state, district, incumbent/challenger, status, and election cycles); or pass candidateId (e.g. P80000722) to get that candidate's aggregate financial totals — total receipts, disbursements, cash on hand, and individual / PAC / party / self contributions in USD for the newest cycle, alongside identity. Free, public-domain (FEC). Search by name first, then pass a returned candidateId back in for the money. For donor/spend diligence, political research, and disclosure lookups.
/api/gov/fecPAYMENT-SIGNATURE.The FEC API exposes US federal campaign finance data from the FEC's openFEC in two modes — candidate search and candidate financial totals — so agents can go from a name to the money in two calls.
Pass name to search candidates (returns FEC candidate id, party, office, state, district, incumbent/challenger status, and election cycles), then pass a returned candidateId (e.g. P80000722) to get aggregate financial totals: total receipts, disbursements, cash on hand, and individual / PAC / party / self contributions in USD for the newest cycle. Public-domain FEC data. No API key — pay per call with x402.
