--- title: List memories url: https://platform.claude.com/docs/en/api/java/beta/memory_stores/memories/list --- # List memories `MemoryListPage beta().memoryStores().memories().list(params = MemoryListParams.none(), requestOptions = RequestOptions.none())` **GET** `/v1/memory_stores/{memory_store_id}/memories` List memories ## Parameters - `MemoryListParams params` - `Optional memoryStoreId` (path parameter) The ID of the memory store to list memories from (`memstore_...`). - `Optional depth` (query 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`. format: int32 - `Optional limit` (query 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. format: int32 - `Optional page` (query 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. - `Optional pathPrefix` (query 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. - `Optional view` (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. - `Optional> 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. - `MESSAGE_BATCHES_2024_09_24("message-batches-2024-09-24")` - `PROMPT_CACHING_2024_07_31("prompt-caching-2024-07-31")` - `COMPUTER_USE_2024_10_22("computer-use-2024-10-22")` - `COMPUTER_USE_2025_01_24("computer-use-2025-01-24")` - `PDFS_2024_09_25("pdfs-2024-09-25")` - `TOKEN_COUNTING_2024_11_01("token-counting-2024-11-01")` - `TOKEN_EFFICIENT_TOOLS_2025_02_19("token-efficient-tools-2025-02-19")` - `OUTPUT_128K_2025_02_19("output-128k-2025-02-19")` - `FILES_API_2025_04_14("files-api-2025-04-14")` - `MCP_CLIENT_2025_04_04("mcp-client-2025-04-04")` - `MCP_CLIENT_2025_11_20("mcp-client-2025-11-20")` - `DEV_FULL_THINKING_2025_05_14("dev-full-thinking-2025-05-14")` - `INTERLEAVED_THINKING_2025_05_14("interleaved-thinking-2025-05-14")` - `CODE_EXECUTION_2025_05_22("code-execution-2025-05-22")` - `EXTENDED_CACHE_TTL_2025_04_11("extended-cache-ttl-2025-04-11")` - `CONTEXT_1M_2025_08_07("context-1m-2025-08-07")` - `CONTEXT_MANAGEMENT_2025_06_27("context-management-2025-06-27")` - `MODEL_CONTEXT_WINDOW_EXCEEDED_2025_08_26("model-context-window-exceeded-2025-08-26")` - `SKILLS_2025_10_02("skills-2025-10-02")` - `FAST_MODE_2026_02_01("fast-mode-2026-02-01")` - `OUTPUT_300K_2026_03_24("output-300k-2026-03-24")` - `USER_PROFILES_2026_03_24("user-profiles-2026-03-24")` - `USER_PROFILES_2026_08_18("user-profiles-2026-08-18")` - `USER_PROFILES_2026_09_04("user-profiles-2026-09-04")` - `ADVISOR_TOOL_2026_03_01("advisor-tool-2026-03-01")` - `MANAGED_AGENTS_2026_04_01("managed-agents-2026-04-01")` - `CACHE_DIAGNOSIS_2026_04_07("cache-diagnosis-2026-04-07")` - `DREAMING_2026_04_21("dreaming-2026-04-21")` - `THINKING_TOKEN_COUNT_2026_05_13("thinking-token-count-2026-05-13")` - `SERVER_SIDE_FALLBACK_2026_06_01("server-side-fallback-2026-06-01")` - `SERVER_SIDE_FALLBACK_2026_07_01("server-side-fallback-2026-07-01")` - `FALLBACK_CREDIT_2026_06_01("fallback-credit-2026-06-01")` - `FALLBACK_CREDIT_2026_07_01("fallback-credit-2026-07-01")` - `AGENT_MEMORY_2026_07_22("agent-memory-2026-07-22")` - `MID_CONVERSATION_TOOL_CHANGES_2026_07_01("mid-conversation-tool-changes-2026-07-01")` - `COMPACT_2026_01_12("compact-2026-01-12")` - `COMPUTER_USE_2025_11_24("computer-use-2025-11-24")` - `MCP_TUNNELS_2026_06_22("mcp-tunnels-2026-06-22")` - `STRUCTURED_OUTPUTS_2025_11_13("structured-outputs-2025-11-13")` - `TASK_BUDGETS_2026_03_13("task-budgets-2026-03-13")` - `THINKING_DISPLAY_UPDATES_2026_08_18("thinking-display-updates-2026-08-18")` - `CE_USER_MANAGEMENT_2026_07_13("ce-user-management-2026-07-13")` - `MID_CONVERSATION_OUTPUT_CONFIG_2026_07_01("mid-conversation-output-config-2026-07-01")` - `THINKING_BINDING_CONTROLS_2026_08_01("thinking-binding-controls-2026-08-01")` - `MID_CONVERSATION_SYSTEM_CLEAR_AT_2026_08_21("mid-conversation-system-clear-at-2026-08-21")` - `COMPACT_2026_09_04("compact-2026-09-04")` - `INLINE_TOOLS_2026_09_15("inline-tools-2026-09-15")` - `MCP_CLIENT_2026_09_15("mcp-client-2026-09-15")` - `CE_PLUGINS_2026_09_01("ce-plugins-2026-09-01")` - `SPEND_LIMIT_READS_2026_09_26("spend-limit-reads-2026-09-26")` - `TELEMETRY_DESTINATIONS_2026_08_11("telemetry-destinations-2026-08-11")` - `Optional 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=java) response: either a `memory` object or, when `depth` is set, a `memory_prefix` rollup marker. - `class BetaManagedAgentsMemory` 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 type` - `String id` Unique identifier for this memory (a `mem_...` value). Stable across renames; use this ID, not the path, to read, update, or delete the memory. - `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`. - `long contentSizeBytes` Size of `content` in bytes (the UTF-8 plaintext length). Always populated, regardless of `view`. format: int32 - `LocalDateTime createdAt` When this memory was created, in RFC 3339 format. format: date-time - `String memoryStoreId` ID of the memory store this memory belongs to (a `memstore_...` value). - `String memoryVersionId` 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](https://platform.claude.com/docs/en/api/beta/memory_stores/memory_versions/list?sdk_languages=java). - `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. - `LocalDateTime updatedAt` 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](https://platform.claude.com/docs/en/api/beta/memory_stores/memory_versions/list?sdk_languages=java). format: date-time - `Optional content` The memory's UTF-8 text content. Populated when `view=full`; `null` when `view=basic`. Maximum 100 kB (102,400 bytes). - `class BetaManagedAgentsMemoryPrefix` A rolled-up directory marker returned by [List memories](https://platform.claude.com/docs/en/api/beta/memory_stores/memories/list?sdk_languages=java) 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 type` - `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 ```java package com.anthropic.example; import com.anthropic.client.AnthropicClient; import com.anthropic.client.okhttp.AnthropicOkHttpClient; import com.anthropic.models.beta.memorystores.memories.MemoryListPage; import com.anthropic.models.beta.memorystores.memories.MemoryListParams; public final class Main { private Main() {} public static void main(String[] args) { AnthropicClient client = AnthropicOkHttpClient.fromEnv(); MemoryListPage page = client.beta().memoryStores().memories().list("memory_store_id"); } } ``` ### 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=" } ```
