The OGC specs for all of WMS, WFS, WCS, and WMTS allow for a metadata_url on a per-layer basis which points to an external document with information about that layer. A number of services include this URL (INSPIRE requires it I believe), however QGIS not only doesn't expose it (https://github.com/qgis/QGIS/issues/31916) - but it would be good if this information was pulled down and represented on the "metadata" tab. Currently that tab is complete empty.
