US Hospitals API
Search and filter more than 5,400 Medicare-certified hospitals across the United States and territories: filter by state, city, free-text name, hospital type (acute care, critical access, psychiatric, childrens, veterans and more), ownership category, whether the hospital offers emergency services, and the CMS overall star rating. Look up any hospital by its CMS facility id, and read metadata listing every state with its hospital count plus the available types and ownership categories for building filter UIs. Each record returns the facility id, name, full address, county, phone number, type, ownership, emergency-services flag and overall rating. Built on the official CMS Hospital General Information dataset. Every endpoint accepts input via the query string or the request body and returns lean JSON. Pure server-side data (no third-party upstream), so responses are instant and always available. Ideal for healthcare directories, patient-facing apps, insurance and care-navigation tools, and research.
