The FEC provides access to campaign finance data, including information on political contributions, campaign expenditures, fundraising activities and financial disclosures filed by political candidates, parties and committees in the United States.
The FEC API provides JSON endpoints for candidates, committees, and financial filings. The `fecfile` Python library parses raw FEC electronic filing data. Engineers use `requests` against the FEC Open Data API with pagination to collect full campaign finance records.
FEC data enables AI tools for campaign finance transparency and political research. Build a RAG system indexed on FEC filings so LLMs can answer 'Who are the top donors to Senate campaigns in 2024?' with official data. AI anomaly detection models trained on FEC data flag suspicious contribution patterns.
