+
+Authoritative DNS analytics are now available on the **account level** via the [Cloudflare GraphQL Analytics API](/analytics/graphql-api/).
+
+This allows users to query DNS analytics across multiple zones in their account, by using the `accounts` filter.
+
+Here is an example to retrieve all DNS queries across all zones in an account that resulted in an `NXDOMAIN` response over a given time frame. Please replace `a30f822fcd7c401984bf85d8f2a5111c` with your actual account ID.
+
+```graphql graphql-api-explorer title="GraphQL example for account-level DNS analytics"
+query Viewer {
+    viewer {
+        accounts(filter: { accountTag: "a30f822fcd7c401984bf85d8f2a5111c" }) {
+            dnsAnalyticsAdaptive(
+                limit: 10
+                filter: { date_geq: "2025-06-16", responseCode: "NXDOMAIN", date_leq: "2025-06-18" }
+                orderBy: [datetime_DESC]
+            ) {
+                zoneTag
+                queryName
+                responseCode
+                queryType
+                datetime
+            }
+        }
+    }
+}
+```
