GET /v1/training/jobs/{job_id}/download This operation is config-only; after normal feature and permission checks, an interactive job ID returns 400, so download a named checkpoint with GET /v1/training/jobs/{job_id}/checkpoints/{checkpoint_id}/download instead. Returns a presigned URL for the trained artifact. Fetch the returned URL separately to download the file.

Request

string

required

Your Fastino API key.

string

required

Temporary presigned artifact URL.

Suggested download file name in the form gliner2-model-<first-8-job-id-characters>.tar.gz.

  "success": true,
  "job_id": "YOUR_TRAINING_JOB_ID",
  "download_url": "https://...",

}

The presigned URL is a temporary bearer credential. Do not log, commit, persist, or share it. Download the artifact promptly and store it according to your data-handling policy.

To request the URL and download the artifact in one workflow:

response=$(curl -fsS \
  https://api.fastino.ai/v1/training/jobs/YOUR_TRAINING_JOB_ID/download \
  -H "X-API-Key: $FASTINO_API_KEY")

curl -fL \
  -o "$(jq -r '.file_name' <<<"$response")" \
  "$(jq -r '.download_url' <<<"$response")"

This example requires jq. Weight downloads are enabled by default. A team whose download access was explicitly disabled receives 403.

Status	Meaning
`400`	For a config job, training is incomplete or its artifact is not ready; wait and retry. For an interactive job ID, use the named-checkpoint download route instead.
`401`	A deferred billing check requires a payment method. Add one in billing settings.
`403`	Weight downloads were explicitly disabled for the team.
`404`	The job is unknown or inaccessible.
