--- title: List Memories url: https://platform.claude.com/docs/en/api/csharp/beta/memory_stores/memories/list --- # 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 memoryStoreID` (path parameter) The ID of the memory store to list memories from (`memstore_...`). - `int depth` (query 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. format: int32 - `int limit` (query 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. format: int32 - `string page` (query parameter) The `next_page` value from a previous response, to get the next page. Omit it to get the first page. - `string pathPrefix` (query 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 view` (query 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 betas` (header parameter) This endpoint is in beta: requests must send `agent-memory-2026-07-22` or `managed-agents-2026-04-01` in this header. - `MessageBatches2024_09_24("message-batches-2024-09-24")` - `PromptCaching2024_07_31("prompt-caching-2024-07-31")` - `ComputerUse2024_10_22("computer-use-2024-10-22")` - `ComputerUse2025_01_24("computer-use-2025-01-24")` - `Pdfs2024_09_25("pdfs-2024-09-25")` - `TokenCounting2024_11_01("token-counting-2024-11-01")` - `TokenEfficientTools2025_02_19("token-efficient-tools-2025-02-19")` - `Output128k2025_02_19("output-128k-2025-02-19")` - `FilesApi2025_04_14("files-api-2025-04-14")` - `McpClient2025_04_04("mcp-client-2025-04-04")` - `McpClient2025_11_20("mcp-client-2025-11-20")` - `DevFullThinking2025_05_14("dev-full-thinking-2025-05-14")` - `InterleavedThinking2025_05_14("interleaved-thinking-2025-05-14")` - `CodeExecution2025_05_22("code-execution-2025-05-22")` - `ExtendedCacheTtl2025_04_11("extended-cache-ttl-2025-04-11")` - `Context1m2025_08_07("context-1m-2025-08-07")` - `ContextManagement2025_06_27("context-management-2025-06-27")` - `ModelContextWindowExceeded2025_08_26("model-context-window-exceeded-2025-08-26")` - `Skills2025_10_02("skills-2025-10-02")` - `FastMode2026_02_01("fast-mode-2026-02-01")` - `Output300k2026_03_24("output-300k-2026-03-24")` - `UserProfiles2026_03_24("user-profiles-2026-03-24")` - `UserProfiles2026_08_18("user-profiles-2026-08-18")` - `UserProfiles2026_09_04("user-profiles-2026-09-04")` - `AdvisorTool2026_03_01("advisor-tool-2026-03-01")` - `ManagedAgents2026_04_01("managed-agents-2026-04-01")` - `CacheDiagnosis2026_04_07("cache-diagnosis-2026-04-07")` - `Dreaming2026_04_21("dreaming-2026-04-21")` - `ThinkingTokenCount2026_05_13("thinking-token-count-2026-05-13")` - `ServerSideFallback2026_06_01("server-side-fallback-2026-06-01")` - `ServerSideFallback2026_07_01("server-side-fallback-2026-07-01")` - `FallbackCredit2026_06_01("fallback-credit-2026-06-01")` - `FallbackCredit2026_07_01("fallback-credit-2026-07-01")` - `AgentMemory2026_07_22("agent-memory-2026-07-22")` - `MidConversationToolChanges2026_07_01("mid-conversation-tool-changes-2026-07-01")` - `Compact2026_01_12("compact-2026-01-12")` - `ComputerUse2025_11_24("computer-use-2025-11-24")` - `McpTunnels2026_06_22("mcp-tunnels-2026-06-22")` - `StructuredOutputs2025_11_13("structured-outputs-2025-11-13")` - `TaskBudgets2026_03_13("task-budgets-2026-03-13")` - `ThinkingDisplayUpdates2026_08_18("thinking-display-updates-2026-08-18")` - `CEUserManagement2026_07_13("ce-user-management-2026-07-13")` - `MidConversationOutputConfig2026_07_01("mid-conversation-output-config-2026-07-01")` - `ThinkingBindingControls2026_08_01("thinking-binding-controls-2026-08-01")` - `MidConversationSystemClearAt2026_08_21("mid-conversation-system-clear-at-2026-08-21")` - `Compact2026_09_04("compact-2026-09-04")` - `InlineTools2026_09_15("inline-tools-2026-09-15")` - `McpClient2026_09_15("mcp-client-2026-09-15")` - `CEPlugins2026_09_01("ce-plugins-2026-09-01")` - `SpendLimitReads2026_09_26("spend-limit-reads-2026-09-26")` - `TelemetryDestinations2026_08_11("telemetry-destinations-2026-08-11")` - `Webhooks2026_10_07("webhooks-2026-10-07")` - `MessageThreads2026_08_12("message-threads-2026-08-12")` - `AnalyticsUsageCost2026_08_24("analytics-usage-cost-2026-08-24")` - `ExperimentalClaudeTag2026_10_21("experimental-claude-tag-2026-10-21")` - `string workspaceID` (header 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](https://platform.claude.com/docs/en/api/beta/memory_stores/memories/list?sdk_languages=csharp) response: a `memory`, or a `memory_prefix` marker when `depth` is `1`. - `class BetaManagedAgentsMemory` 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](https://platform.claude.com/docs/en/managed-agents/memory?sdk_languages=csharp#view-and-edit-memories) to learn more about working with memories. - `JsonElement Type = "memory"` - `required string ID` The unique ID of the memory (`mem_...`). It stays the same when the memory's path changes. To retrieve, update, or delete the memory, pass this ID. - `required string ContentSha256` 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`. - `required int ContentSizeBytes` The size of the memory's `content` in UTF-8 bytes. It is set regardless of `view`. format: int32 - `required DateTimeOffset CreatedAt` When this memory was created, in RFC 3339 format. format: date-time - `required string MemoryStoreID` ID of the memory store this memory belongs to (a `memstore_...` value). - `required string MemoryVersionID` The ID of the memory version that holds the memory's current content (`memver_...`). Memory versions don't have a flag that marks the latest one. Compare their IDs with this field instead. See the [memory guide](https://platform.claude.com/docs/en/managed-agents/memory?sdk_languages=csharp#audit-memory-changes) to learn more about memory versions. - `required string Path` 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. - `required DateTimeOffset UpdatedAt` When the memory was last changed, in RFC 3339. To find out who made the change, look at `created_by` on the memory version that `memory_version_id` references. format: date-time - `string? Content` The memory's UTF-8 text content, or `null` when the response uses `view=basic`. The maximum size is 100 kB (102,400 bytes). - `class BetaManagedAgentsMemoryPrefix` A directory marker that [List Memories](https://platform.claude.com/docs/en/api/beta/memory_stores/memories/list?sdk_languages=csharp) 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. ## Example ```csharp 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); } ``` ### Response (200) ```json { "data": [ { "id": "mem_011CZkZ9X2dpNyB6YbtxvB6e", "content_sha256": "ba7936d94c84d948a2232088f78228f175df6a8353b2d5bc9228eee5794a0024", "content_size_bytes": 28, "created_at": "2026-03-15T10:00:00Z", "memory_store_id": "memstore_01Wf3kQ8tZxB2mVr7HcJ4aNd", "memory_version_id": "memver_011CZkZBJq5dWxk9fVLNcPht", "path": "/preferences/formatting.md", "type": "memory", "updated_at": "2026-03-15T10:00:00Z", "content": null } ], "next_page": "page_MjAyNS0wNS0xNFQwMDowMDowMFo=" } ```
