Returns CMS Open Payments records — the Sunshine Act database of every payment / transfer of value from drug + device manufacturers and GPOs to US physicians, non-physician practitioners, and teaching hospitals (~15M records per program year, 2019→present)
Returns CMS Open Payments records — the Sunshine Act database of every payment / transfer of value from drug + device manufacturers and GPOs to US physicians, non-physician practitioners, and teaching hospitals (~15M records per program year, 2019→present). LIVE passthrough to CMS's own API: results reflect CMS's current data and total_count is CMS's authoritative count for the filtered query (the results array is just the requested page). Use this when the user asks about: pharma/device money to doctors, a company's physician-payment footprint, speaker-fee / consulting / royalty programs, industry funding of research (with ClinicalTrials.gov IDs), or physician ownership stakes in manufacturers. payment_type selects the dataset (schemas differ; rows are CMS's fields verbatim): general (default) — meals, travel, consulting, speaker fees, royalties, honoraria. Fields incl. nature_of_payment_or_transfer _of_value, name_of_drug_or_biological_or_device_or_medical supply_1, covered_recipient_specialty_1. research — research payments incl. name_of_study, clinicaltrials_gov_identifier, preclinical_research_indicator. ownership — physician ownership/investment interests (total_amount_invested_usdollars, value_of_interest, terms_of_interest); recipient fields are physician*. summarize=true returns CMS's own pre-aggregated per-(company, nature) totals for the year — transaction counts + dollar totals per payment nature. The nature codes in that dataset ship without a public CMS legend; KeyVex labels the seven codes it has VERIFIED by exact count+total reconciliation against detail data (1=Consulting Fee, 2=Speaker/faculty compensation, 6=Food and Beverage, 7=Travel and Lodging, 9=Charitable Contribution, 10=Royalty or License, 14=Grant); unverified codes pass through with an empty label rather than a guess. Matching: company is a substring (matches subsidiaries: 'pfizer' catches PFIZER INC.); recipient names are EXACT (CMS stores uppercase; we uppercase for you); npi is the exact National Provider Identifier — the precise join key to get_oig_exclusions. Payments are attributed to the manufacturer AS FILED — no ticker/CIK; try the operating-company name. Program years: 2019 through the latest published year (CMS refreshes semiannually; year defaults to the latest). Pagination: limit ≤ 500 per page (CMS cap), use offset for more. Pure-publisher posture: CMS's records as filed, parsed by KeyVex (the source record is authoritative) — no derived influence scores. Disclosure ≠ wrongdoing; these are lawful, statutorily-disclosed payments.
