Open Settings, then API access. Each key shows its label, the start of the key, and when it was last used. Harbour GIS layer was used this morning.

The GIS layer has been replaced. Choose Revoke on its row, then Revoke key. Anything still using it is refused on its next request. It cannot be undone: create another key if you need one.
