What a record looks like in the API response.
{
"resourceType": "Organization",
"id": "snf-owner-015009-entity-1",
"_source": "cms-snf-owners",
"_methodology": "snf-owners/v1",
"name": "Example SNF Operating LLC",
"extension": [{ "url": "ownershipPercentage", "valueDecimal": 0.51 }]
}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.
