FHIR Location · Sample record

What a record looks like in the API response.

Sample record
{
  "resourceType": "Location",
  "id": "pos-015009",
  "_source": "cms-pos",
  "_methodology": "cms-pos/v1",
  "identifier": [{ "system": "http://hl7.org/fhir/sid/us-ccn", "value": "015009" }]
}

Every record carries _source, _methodology, a snapshot date, and a confidence tier. All fourteen provenance fields survive export and API delivery.

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.
