description: CMS Open Payments is the U.S. federal transparency program (run by the Centers for Medicare and Medicaid Services)
  that publishes payments and transfers of value made by drug and medical device manufacturers and group purchasing organizations
  to physicians, non-physician practitioners, and teaching hospitals. The public data site at openpaymentsdata.cms.gov exposes
  a free, open, no-authentication REST API (a DKAN-style data catalog under /api/1) that lets developers query general payments,
  research payments, and ownership and investment records by program year. The API offers a structured datastore query interface
  (filter, select, sort, paginate), a SQL query endpoint, CSV and JSON downloads, and a metastore catalog for dataset discovery
  and metadata. Reads are completely free and require no API key. Program Year 2025 alone contains roughly 17 million published
  records totaling about 14.67 billion dollars in payments.
