# Download Code Artifact Version Content

**GET** `/v1/compliance/apps/code/artifacts/{artifact_id}/versions/{version_id}`

Streams the content of one version of a Claude Code Artifact as the
response body.

Returns 404 for Artifacts that don't exist or belong to another parent
organization. A listed version id can start returning 404 if subsequent
publishes rotated it out of retained history — re-list on 404. Returns
503 while the version's content upload is still in flight or was
abandoned — retry with backoff. Returns 422 with
`error.details.error_code` `multi_file_unavailable` for a version that
has more than one file, unless the request sets `multi_file_format=zip`,
which returns those files as a ZIP archive. With `multi_file_format=zip`,
a version with more than one file, one of them with a name the API cannot
export, gets 422 `file_set_unavailable`. Do not retry a 422. A Claude
Doc's versions hold only the web page that displays the Doc and never come
back as a ZIP. That page usually has more than one file, so a Doc's version
usually gets the 422 `multi_file_unavailable`. Download the Doc's text with
`GET /v1/compliance/apps/code/artifacts/{artifact_id}/content?multi_file_format=zip`.
Oversized encoded content aborts mid-stream: headers and initial bytes arrive
but the body terminates early — an aborted chunked transfer is the
only truncation signal for encoded content. `Content-MD5` is emitted
only for identity-stored content; validate against it when present.

## Path parameters

- `artifact_id: string`

  The Artifact ID (tagged ID, e.g., cart_abc123)

- `version_id: string`

  Opaque version identifier from the Artifact's `versions` list

## Query parameters

- `multi_file_format: optional string`

  Set to `zip`, its only value, to receive a version that has more than one file as a ZIP archive of its files with an index, `files.json`. Files the Artifact copied from its type (the app that displays every Artifact of that type) are listed under `omitted_files` in the index, and left out of the archive, when an organization other than the Artifact's owns that type. Files the version uses from another Artifact are always listed there and left out. A Claude Doc's version never comes back as a ZIP: it is answered as without this parameter, except that a version with more than one file, one of them with a name the API cannot export, gets 422 `file_set_unavailable`. A version with one file is returned as that file, as without this parameter.
