Data source

All data comes from the U.S. Senate Office of Public Records via their official REST API. Data covers filings from 2000 to present (contributions from 2008).

Limits

• The Senate API returns max 25 results per page, so large datasets require many requests
• With an API key: ~120 pages/min. Without: ~15 pages/min
• Some very old filings may have incomplete data
