Screenly is a distribution layer, not an archive. A file you delete cannot be recovered by support.
Keep your originals in your own storage: a file server, cloud storage, or whatever asset management your organization already runs.
Retrieving what is there
Every asset has a source_url pointing at the original file, and both the CLI and the API return it.
With the CLI:
screenly asset list --json | jq -r '.[] | {title, source_url}'With the API, the assets endpoint returns the same field. For a handful of files, fetch them by hand. For a library, script it.
Before you cancel
Do this while the subscription is still active. Take the export first, then cancel. See Managing your subscription.
