+## Special limit feature for job events
+
+Use the `limit` query string parameter to opt out of the pagination keys.
+Doing this can improve response times for jobs that produce a large volume
+of outputs.
+
+    ?limit=25
+
+This will set the page size to 25 and the `previous` and `next` keys will be
+omitted from the response data. The data structure will look like this.
