# List Key Occurrences

`GET /v1/projects/{project_id}/keys/{key_id}/occurrences`

## Request

- Base URL: `https://api.sonenta.dev`
- URL: `https://api.sonenta.dev/v1/projects/{project_id}/keys/{key_id}/occurrences`
- Auth: none declared

Every file that references THIS key, joined by stable key_uuid (Viewer+).

The per-key panel of the 'par fichier' translation view. 404 if the key does
not exist, so an empty list always means 'no known usage sites', never 'no
such key'. `measured=false` means no scan has completed — 'never scanned', not
'referenced nowhere'.
