# GET /experimental/launch-runs/{id}/artifact

`GET /experimental/launch-runs/{id}/artifact`

Returns a presigned URL for downloading the diagnostic workspace archive a launch run execution retained. Every execution retains an archive, success or failure alike. Requires workspace-admin permission because the archive is a raw workspace snapshot that can contain secrets a recipe or agent wrote. Pass `attempt` to download a specific execution’s archive (see the per-execution list at `/launch-runs/:id/executions`); omit it for the latest execution.
