List memories

$ ant beta:memory-stores:memories list
GET/v1/memory_stores/{memory_store_id}/memories

List memories

Parameters
--memory-store-id: string⁠Path parameter

The ID of the memory store to list memories from (memstore_...).

--depth: optional number⁠Query parameter

0 (or omitted) returns all descendants below path_prefix (recursive). 1 returns immediate children only; deeper entries roll up as memory_prefix items. depth=1 behaves like ls; omitting depth behaves like find.

formatint32
--limit: optional number⁠Query parameter

Maximum number of items to return per page. Must be between 1 and 100. Defaults to 20 when omitted. Capped at 20 when view=full. Both memory and memory_prefix items count toward the limit.

formatint32
--page: optional string⁠Query parameter

Opaque pagination cursor (a page_... value). Pass the next_page value from a previous response to fetch the next page; omit for the first page.

--path-prefix: optional string⁠Query parameter

Optional path prefix filter. Must end with / (segment-aligned), e.g., /notes/. This value appears in request URLs. Do not include secrets or personally identifiable information.

--view: optional "basic" or "full"⁠Query parameter

Which projection of each memory to return. Defaults to basic (content omitted). full populates content on each item and caps limit at 20; use this as the bulk-read path for export and sync.

--beta: optional array of AnthropicBeta⁠Header parameter

This endpoint is in beta: requests must send agent-memory-2026-07-22 or managed-agents-2026-04-01 in this header.

--workspace-id: 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
BetaManagedAgentsListMemoriesResult: object{ data, next_page }

Response payload for List memories.

data: optional array of BetaManagedAgentsMemoryListItem

One page of results. Each item is either a memory object or, when depth was set, a memory_prefix rollup marker. Items are returned in a stable, server-defined order.

One of the following:
beta_managed_agents_memory: object{ type: "memory", id, content_sha256, 7 more }

A memory object: a single text document at a hierarchical path inside a memory store. The content field is populated when view=full and null when view=basic; the content_size_bytes and content_sha256 fields are always populated so sync clients can diff without fetching content. Memories are addressed by their mem_... ID; the path is the create key and can be changed via update.

type: "memory"
id: string

Unique identifier for this memory (a mem_... value). Stable across renames; use this ID, not the path, to read, update, or delete the memory.

content_sha256: string

Lowercase hex SHA-256 digest of the UTF-8 content bytes (64 characters). The server applies no normalization, so clients can compute the same hash locally for staleness checks and as the value for a content_sha256 precondition on update. Always populated, regardless of view.

content_size_bytes: number

Size of content in bytes (the UTF-8 plaintext length). Always populated, regardless of view.

formatint32
created_at: string

When this memory was created, in RFC 3339 format.

formatdate-time
memory_store_id: string

ID of the memory store this memory belongs to (a memstore_... value).

memory_version_id: string

ID of the memory_version representing this memory's current content (a memver_... value). This is the authoritative head pointer; memory_version objects do not carry an is_latest flag, so compare against this field instead. Enumerate the history via List memory versions.

path: string

Hierarchical path of the memory within the store, e.g. /projects/foo/notes.md. Always starts with /. Paths are case-sensitive and unique within a store. Maximum 1,024 bytes.

updated_at: string

When this memory was last modified, in RFC 3339 format. Use this as a cheap freshness signal; for who made the change, look up the head version's created_by via List memory versions.

formatdate-time
content: optional string

The memory's UTF-8 text content. Populated when view=full; null when view=basic. Maximum 100 kB (102,400 bytes).

beta_managed_agents_memory_prefix: object{ type: "memory_prefix", path }

A rolled-up directory marker returned by List memories when depth is set. Indicates that one or more memories exist deeper than the requested depth under this prefix. This is a list-time rollup, not a stored resource; it has no ID and no lifecycle. Each prefix counts toward the page limit and interleaves with memory items in path order.

type: "memory_prefix"
path: string

The rolled-up path prefix, including a trailing / (e.g. /projects/foo/). Pass this value as path_prefix on a subsequent list call to drill into the directory.

next_page: optional string

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