Published cadence
Every dataset refreshed on a documented schedule tied to CMS release dates.
Row-level provenance
14 provenance fields per value. Source, snapshot date, methodology, confidence — all survive export.
FHIR R4 resource
Every dataset is exposed as a USCDI v3 FHIR R4 resource for agent and EHR integrations.
How it works
Federal data → field-level provenance → your agent.
Every row Fonteum returns is traceable back to the exact federal release that produced it. No opaque pipeline. No synthetic fills.
01
Federal source pull
Inngest workers pull from CMS, HHS-OIG, HRSA, BLS, and BEA on each agency's published release cadence. Every pull is SHA-256 attested.
02
14-tuple provenance binding
Each field is bound to source, snapshot date, methodology version, confidence tier, and eleven more fields. All travel with exports and API responses.
03
FHIR R4 + CSV delivery
Every dataset is available as a USCDI v3 FHIR R4 resource and as a gzipped CSV with SHA-256 integrity header. Request access for the pilot API key.
All datasets
14 dataset pages.
CMS and HHS-OIG sources. Nursing facilities, provider performance, sanctions, hospital financials, and care quality.

Row-level provenance on every field
A 14-tuple provenance contract.
Every value Fonteum returns is bound to fourteen provenance fields. All fourteen survive export — a buyer who receives a Fonteum record can trace any field back to the exact federal release that produced it.
Federal source pull
SHA-256 attested snapshot of the raw agency file. Snapshot date and file hash recorded in ingestion_runs.
Column → field mapping
Every source column is mapped to a canonical field with a typed parser. Mapping version is pinned in _methodology.
14-tuple binding
Each field gets _source, _snapshot, _confidence, and eleven more. All fields travel with FHIR meta.tag and CSV export.
Why it's defensible
The moat compounds with every source family.
Federal data is public. The moat is the engineering layer on top of it — provenance depth, schema consistency, and FHIR compatibility that only compound over time.
Cross-source joins
CCN identity backbone (CMS POS) lets us join nursing home, dialysis, hospice, and staffing data deterministically. Competitors who start fresh pay 18+ months to get there.
Methodology versioning
Every column mapping is a versioned artifact. When CMS changes a schema, we ship a new methodology version — prior snapshots remain traceable to the version that produced them.
FHIR R4 from day one
USCDI v3 resource mapping for all five provider resource types. Agents and EHRs that speak FHIR get a zero-translation integration path.
Public-domain foundation
U.S. Government Works upstream. No NMLS. No state bar. No ABMS. No data that can be yanked by a licensor. The raw data is yours too — what you're licensing is the provenance layer.
