+      description: |
+        This resource is used to match a list of Companies to check that they
+        have an active integration with a partner fetching from their company inbox
+        and are eligible for receiving Content from a specific Tenant.
+
+        **Note:**
+        This is only for specific use cases, and will not give you all eligible recipients.
+        You most likely want to use [the regular company match](#tag/Tenant-API-Content/operation/Match%20Companies%20VatNr%20v2).
+
+        The request contains a list of VAT numbers to be matched, and
+        the response is a filtered subset of said list containing only
+        those VAT numbers matching a Company Recipient for which the Tenant
+        is eligible to send Content to, and have an active partner integration.
+
+        <aside class="notice">
+          If none of the provided VAT numbers match a Recipient eligible to receive content from the given Tenant, an empty list will be returned.
