How this service works
US federal campaign contributions (FEC Schedule A itemized receipts) from the official OpenFEC API, by contributor name, employer, committee ID or state for a two-year cycle: contributor, employer, occupation, city/state/ZIP, amount, date, committee, receipt type, memo and filing image link, newest first, with total count. FEC law forbids using contributor names for solicitation or commercial purposes.
Output
Returns a JSON object containing: the election cycle, total number of matching records, source URL used to query the FEC API, a checkedAt timestamp, and an array of contribution records. Each record includes contribution ID, contributor name, employer, occupation, city, state, zip, date, amount, receipt type, memo text, the receiving committee (ID, name, party), and a link to the FEC filing image document.
Example use cases

“Show me all campaign finance contributions from Google employees in the 2024 election cycle, with a minimum amount of $1,000, up to 50 results.”
Committee fundraising audit
“Pull up the most recent 30 contributions received by committee C00703975 in the 2024 cycle from the FEC database.”
State-level donor pattern analysis
“Find campaign contributions from donors in Texas during the 2022 election cycle with amounts of at least $500 — give me up to 100 records.”
Technical details
Endpoint
GEThttps://api.chainmarket-api.workers.dev/api/finance/fec-campaign-finance-contributions?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, filterable FEC Schedule A individual contribution data without setting up an FEC API key or account. It is ideal for AI agents doing one-off or pay-per-call political finance lookups, especially when filtering by employer, state, or minimum amount. Prefer this over direct FEC API calls when you want a zero-signup, micropayment-gated interface with a clean JSON response and example data.
Side effects
- Contributor name searches can take ~20 seconds due to FEC backend latency
- Invalid committee ID returns empty results or FEC error
- Unsupported cycle year (outside current and recent cycles) may return no data
- Rate limiting or FEC API downtime causes upstream failure
- Payment not charged on failed calls; 402 response if payment header is missing
