+    options.MapEndpoints(useSystemJson:UseSystemJson.Always);
+
+    // Use only for deserializing API Requests
+    options.MapEndpoints(useSystemJson:UseSystemJson.Request);
+
+    // Use only for serializing API Responses
+    options.MapEndpoints(useSystemJson:UseSystemJson.Response);
+
+    // Don't use System.Text.Json for APIs
+    options.MapEndpoints(useSystemJson:UseSystemJson.Never);
+});
+```
