- `"anthropic-workspace-id": optional string`

  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

- `data: optional array of BetaManagedAgentsMemoryStore`

  Memory stores on this page, newest first. Empty when there are no stores matching the filters.

  - `type: "memory_store"`

  - `id: string`

    Unique identifier for the memory store (a `memstore_...` tagged ID). Use this when attaching the store to a session, or in the `{memory_store_id}` path parameter of subsequent calls.

  - `archived_at: string or null`

    Timestamp when the store was archived, or `null` if active. Set once and never cleared; archiving is one-way. Archived stores are read-only and cannot be attached to new sessions.

    format: date-time

  - `created_at: string`

    Timestamp when the store was created.

    format: date-time

  - `description: string`

    Free-text description of what the store contains, up to 1024 characters. Included in the agent's system prompt when the store is attached, so word it to be useful to the agent. Empty string when unset.

  - `metadata: map[string]`

    Arbitrary key-value tags for your own bookkeeping (such as the end user a store belongs to). Up to 16 pairs; keys 1–64 characters; values up to 512 characters. Returned on retrieve/list but not filterable.

  - `name: string`

    Human-readable name for the store. 1–255 characters. The store's mount-path slug under `/mnt/memory/` is derived from this name.

  - `updated_at: string`

    Timestamp when the store's `name`, `description`, or `metadata` was last modified. Memory writes inside the store do not advance this.

    format: date-time

- `next_page: optional string or null`

  Opaque cursor for the next page (a `page_...` value). Pass as `page` on the next request. `null` when there are no more results.
