Requests that return no result

By default, FDSN services return an HTTP code of 204 when a request is “successful”, but there were no matching results. This behavior allows automated systems to know the difference between a successful request (with no data) from an incorrect request (bad parameter names, invalid URL, etc). Since no content is returned, the page on the web browser will not change. To force the service to return a 404, add the query parameter nodata=404.
