Pilot, standard, and enterprise customers receive audit packs scoped to their contracted dataset list and delivery cadence. Methodology version is pinned to the snapshot they received. Rollback to a prior version is documented in the change history.

API export endpoint

Bulk export for contracted customers.

Contracted pilots get programmatic access via /api/v1/audit-pack/export. The endpoint returns NDJSON, JSON, or CSV. Source inventory is drawn from the SPRINT1_EXPORT_SOURCES registry (44 federal source families, row-level provenance on every field).

# Sample request

curl -H "Authorization: Bearer fnt_<your_key>" \

"https://fonteum.com/api/v1/audit-pack/export?format=ndjson"

Row-level provenance fields travel with every exported record: source, snapshot date, methodology version, confidence tier. Export keys are issued at pilot onboarding. Contact pilot@fonteum.com to request a key.

Built on the authoritative federal record

The primary sources, named on every page.

These are the federal agencies whose public datasets Fonteum ingests and attributes — the issuing authorities, not customers or partners. Every figure on the site links back to one of them.

  • CMS
  • HHS-OIG
  • HRSA
  • FDA
  • NLM
  • NUCC
  • Census
  • BLS
  • BEA

Reproducible by design

Every figure traces to its federal source.

14-tuple provenance

Every rendered fact ties to a source URL, dataset ID, snapshot date, row key, and SHA-256 — the full chain-of-custody record.

Reproducible SQL

Each study ships the exact query behind its figures, run against the cited federal snapshot. Re-run it yourself.

Daily reconciliation

Published counts are reconciled against the upstream federal datasets on a daily cadence, with drift logged.

Named medical review
