"_methodology": "care-compare-asc/v1",
"type": [{ "text": "Ambulatory Surgical Center" }]
}Every record carries _source, _methodology, a snapshot date, and a confidence tier. These provenance fields survive export and API delivery — each fact stays chained to the federal release it came from.

One request returns a provenance-tracked record.
curl -H "Authorization: Bearer $FONTEUM_KEY" \ "https://api.fonteum.com/fhir/r4/Location?_source=asc" \ | jq '._source, ._methodology, .meta.tag'
