Technical details
Endpoint
GEThttps://2s.io/api/gov/congress-amendmentWhen to prefer
Use this endpoint when you need structured data about US Congressional amendments from Congress.gov, especially when you need sponsor information and full action history for a specific amendment, or when filtering amendments by type and date range.
