Provider 360 — everything we know about a US healthcare provider, merged on their 10-digit NPI in one call. Combines three federal datasets: identity (NPPES registry: name, specialty/taxonomy, practice address, licenses), industry payments (CMS Open Payments: what drug & device makers paid them), and Medicare billing (CMS Physician & Other Practitioners: services, charges, and Medicare payment amounts). Each section reports found/error independently — a provider with no Open Payments or Medicare record still returns identity. KYC, healthcare-fraud research, investigative journalism, provider due diligence. Pass npi (required). For the individual sources see /api/license/medical, /api/health/open-payments, /api/health/medicare-provider.
