List Memories

MemoryListPage Beta.MemoryStores.Memories.List(parameters, cancellationToken = default)
GET/v1/memory_stores/{memory_store_id}/memories

List Memories

Parameters
MemoryListParams parameters
required string memoryStoreID⁠Path parameter

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

int depth⁠Query parameter

How far below path_prefix to list. Defaults to 0, which lists every memory below the prefix.

Pass 1 to list only the direct children. Deeper memories are then grouped into memory_prefix items.

formatint32
int limit⁠Query parameter

The maximum number of items to return per page, from 1 to 100. Defaults to 20.

With view=full, a page holds at most 20 items. memory and memory_prefix items both count toward the limit.

formatint32
string page⁠Query parameter

The next_page value from a previous response, to get the next page. Omit it to get the first page.

string pathPrefix⁠Query parameter

Return only memories whose path starts with this prefix, such as /notes/. This value appears in request URLs. Do not include secrets or personally identifiable information.

Omit it to list the whole store. The prefix must end with / and matches whole segments, so /notes/ matches /notes/todo.md but not /notes-archive/todo.md.

BetaManagedAgentsMemoryView view⁠Query parameter

Whether each memory in the response includes content. Defaults to basic, which sets it to null.

With full, a page holds at most 20 items.

IReadOnlyList<AnthropicBeta> betas⁠Header parameter

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

string workspaceID⁠Header 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 BetaManagedAgentsMemoryListItem: union

One item in a List Memories response: a memory, or a memory_prefix marker when depth is 1.

class BetaManagedAgentsMemory { Type = "memory"; ID; ContentSha256; /* 7 more */ }

A text document at a path inside a memory store.

content is null when the response uses view=basic. content_size_bytes and content_sha256 are always set, so you can detect changes without fetching the content. To retrieve, update, or delete a memory, pass its ID, which stays the same when its path changes.

See the memory guide to learn more about working with memories.

class BetaManagedAgentsMemoryPrefix { Type = "memory_prefix"; Path; }

A directory marker that List Memories returns instead of the memories below the requested depth.

It stands for one or more memories whose paths start with path. It isn't a stored object and doesn't have an ID. Each marker counts toward the page limit.

JsonElement Type = "memory_prefix"
required string Path

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.

List Memories
using System;
using Anthropic.Models.Beta.MemoryStores.Memories;

MemoryListParams parameters = new() { MemoryStoreID = "memory_store_id" };

var page = await client.Beta.MemoryStores.Memories.List(parameters);
await foreach (var item in page.Paginate())
{
    Console.WriteLine(item);
