  "raw_analysis": "OpenFEC is the official RESTful API from the U.S. Federal Election Commission (FEC), providing programmatic access to federal campaign finance data. The platform (fec.gov) is a public government website serving candidates, committees, journalists, researchers, and the general public. The API is mature, well-documented (Swagger UI at api.open.fec.gov/developers), and open source on GitHub. Authentication uses a free API key issued through api.data.gov (an EPA/GSBA shared key service); a DEMO_KEY exists but with severe limits. Endpoints cover candidates, committees, schedules A/B/E, reports, filings, elections, and legal resources. Data is authoritative and updated as filings are processed. No paid tier; it is a public good service. Integrations are primarily through direct HTTP access, though bulk data downloads and the fec.gov website itself consume the same API. Maturity: stable, versioned (v1), actively maintained. Limitations: rate limits, some latency due to filing processing, and historical data coverage caveats."
