Maximum number of items to return.

Response

Envelope containing an items array of checkpoint records with fields such as id, job_id, step, metric snapshots, artifact_paths, and created_at.

Example

curl https://ariapin.example.com/v1/checkpoints \
  -H "Authorization: Bearer $ARIAPIN_API_KEY"

{
  "code": 0,
  "data": {
    "items": [
      {
        "id": "ckpt_0198c...",
        "job_id": "job_0198a...",
        "step": 500,
        "created_at": "2025-09-01T12:00:00Z"
      }
    ]
  },
  "message": ""

Checkpoints and models share the same underlying storage. Use List Models when you need per-model lifecycle actions such as merge, reload, or export.
