Archive a Dream

$client->beta->dreams->archive(string dreamID, ?list<AnthropicBeta> betas, ?string workspaceID): BetaDream
POST/v1/dreams/{dream_id}/archive
Requires anthropic-beta: dreaming-2026-04-21. How to send beta headers

Hide a completed, failed, or canceled dream from the default list of dreams.

Archiving a pending or running dream returns a 400 error, so cancel it first. Archiving an archived dream returns it unchanged. An archived dream can still be fetched by ID. Archiving can't be undone.

See the Dreams guide to learn more about archiving dreams.

Parameters
dreamID: string⁠Path parameter

The ID of the dream to archive (drm_...).

betas?: optional list<AnthropicBeta>⁠Header parameter

This endpoint is in beta: requests must send dreaming-2026-04-21 in this header.

workspaceID?: optional string⁠Header parameter

Optional header to select the Workspace for this request. The value is a Workspace ID (for example, wrkspc_011CZkZaBF1tNoB5wlCeusgy).

Only needed for credentials that can act on more than one Workspace. A credential that belongs to a specific Workspace may omit it; if sent, it must match that Workspace.

Returns
class BetaDream { $type = 'dream'; $id; $archivedAt; /* 11 more */ }
