Tools

Tool	Description
`open_payments_search`	Search one CMS Open Payments program-year dataset using structured recipient, company, product, geography, payment-nature, and amount filters. CMS publishes company-reported relationships; a payment does not imply wrongdoing or a conflict.
`open_payments_physician`	Find CMS Open Payments records for a physician/non-physician practitioner by exact NPI in one program year. Returns the authoritative total match count plus a bounded payment sample; reported relationships do not imply misconduct. If you have a name rather than an NPI, resolve it first against the NPPES registry (npi_individual in the clinicaltables pack), or use open_payments_search with recipient_last_name + recipient_first_name.
`open_payments_company`	Search payments reported by a manufacturer or GPO in one CMS Open Payments program year. Company matching is a case-insensitive substring and may combine similarly named legal entities.
`open_payments_product`	Search general-payment records associated with a named drug, biologic, device, or medical supply across all five CMS product slots. Product association is reporting-entity supplied and does not prove the payment was exclusively for that product.
`open_payments_research`	Search CMS research-payment records by company, recipient NPI, study name, or state for one program year. Amounts may represent funding routed through an institution and should not automatically be attributed as personal compensation.
