Open Payments Plans Pricing

The CMS Open Payments data API is a free public good. It is operated by the U.S. Centers for Medicare and Medicaid Services and funded by the federal government, so there is no pricing, no metering, and no account required to read the data. Every endpoint - metastore catalog, search, datastore query, SQL, and CSV/JSON download - is available anonymously at no cost. The underlying records are U.S. government works in the public domain and may be reused, including commercially, subject to CMS data use guidance.
