Available fields

  • Book and series IDs
  • Recorded memberships
  • Known positions and record versions

A recorded position is not a recommended reading order.

Integration details

Numbering can vary between editions and markets, and some series have unnumbered companions. Preserve those distinctions. Do not turn a missing position into a guessed sequence.

GET /v2/works/{work_id}

Shortened example; replace example IDs with IDs returned by the API.

{
  "data": {
    "work": {
      "series": [
        {
          "id": "sts_example",
          "name": "Example series",
          "position": null
        }
      ]
    }
  }
}

Coverage varies. Check the titles important to your product before relying on a complete order. The API does not supply dedicated reading-order guides.

Keep keys on your server. Save matched IDs and compare record versions when refreshing data. Missing fields should not overwrite good values in your catalog.

Access is by approval. Commercial storage and reuse follow your agreed terms. Ebook files, inventory and cover-image redistribution rights are outside the API.
