Fonteum is a public-records research and screening platform that helps users look up providers, companies, sanctions, and enforcement records and trace findings back to their issuing sources. It brings together data from US public agencies and selected UK and Australian company registers, alongside worldwide sanctions sources. Coverage includes healthcare provider and facility records, federal exclusions, sanctions, contracting information, enforcement actions, and filings.

Designed for compliance teams, healthcare organizations, journalists, researchers, developers, and AI teams, Fonteum supports exclusion and sanctions screening, credentialing and provider-data enrichment, audit documentation, and business or network diligence. Users can search individual records or screen the first 25 provider NPIs on screen at no cost; a one-off certificate for up to 25 NPIs is also offered for $129. Developers can access records through a REST API, bulk access, an MCP server, and a FHIR R4 API.

Fonteum displays source, date, and limitations with returned facts, and provides links to original records and signed receipts for captured source artifacts.
