REST API live today; Delta Sharing + Snowflake Secure Data Share Q3 2026; S3 + Databricks Marketplace Q4 2026; Salesforce Data Cloud + SFTP available on request. Every entry below is dated and verifiable. Procurement teams: see /trust/data-provenance for the upstream license posture.
Live today. NDJSON streaming export with field allowlists, delta logs, and metadata header. CCN-anchored hydration for Care Compare datasets. OpenAPI spec at /api/v1/openapi.json. Pilot tier ships with 1 dataset/month AI-native export + daily refresh on the selected dataset.
Per-customer SFTP delivery available on request for partners whose internal compliance review prohibits API consumption. Cadence aligned with manifest snapshot frequency (see /sources/cadence). Encrypted at rest + in transit.
Sprint 2 priority — target Q3 2026. Native Delta Sharing endpoint exposes audit-pack-aligned tables with field-level provenance preserved as metadata columns. Partners can consume via Databricks, Apache Spark, pandas, or any Delta Sharing client without custom integration.
Sprint 2 priority — target Q3 2026. Same data surface as Delta Sharing, exposed natively in Snowflake's secure-share mechanism. Zero-copy share — partners read live from Fonteum's Snowflake account on subscription, no replication or staging required.
Q4 2026 target. S3-bucket-listed datasets with bucket-policy-based access control + Databricks Marketplace listing for one-click subscription by Databricks customers. Same audit-pack provenance contract; partners pay Fonteum directly, marketplace handles billing handshake.
Available on request for partners with active Salesforce Data Cloud licensing. Same data surface as Delta Sharing, exposed natively as a Data Cloud ingestable. Zero-copy — partners query live from Fonteum without replicating into Data Cloud storage.
REST, Delta Sharing, Snowflake Secure Share, S3, and Salesforce Data Cloud all expose the same Fonteum audit-pack-aligned schema. Field-level source / last-checked-date / limitations metadata travels with the data — partners never receive an unannotated row. The methodology version is pinned per delivery; the Audit Pack PDF + JSON ship alongside every customer-scoped delivery for compliance attachment.

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.

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.
