--- title: List memories url: https://platform.claude.com/docs/en/api/python/beta/memory_stores/memories/list --- # List memories `beta.memory_stores.memories.list(memory_store_id, **kwargs) -> SyncPageCursor[BetaManagedAgentsMemoryListItem]` **GET** `/v1/memory_stores/{memory_store_id}/memories` List memories ## Parameters - `memory_store_id: str` (path parameter) The ID of the memory store to list memories from (`memstore_...`). - `depth: Optional[int]` (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 - `limit: Optional[int]` (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 - `page: Optional[str]` (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. - `path_prefix: Optional[str]` (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. - `view: Optional[BetaManagedAgentsMemoryView]` (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. - `"basic"` Return the object with `content` set to `null`. The `content_size_bytes` and `content_sha256` fields remain populated, so sync clients can diff without fetching content. - `"full"` Return the object with `content` populated. On list endpoints, `view=full` caps `limit` at 20. - `betas: Optional[List[AnthropicBetaParam]]` (header parameter) Optional header to specify the beta version(s) you want to use. - `str` - `"message-batches-2024-09-24"` - `"prompt-caching-2024-07-31"` - `"computer-use-2024-10-22"` - `"computer-use-2025-01-24"` - `"pdfs-2024-09-25"` - `"token-counting-2024-11-01"` - `"token-efficient-tools-2025-02-19"` - `"output-128k-2025-02-19"` - `"files-api-2025-04-14"` - `"mcp-client-2025-04-04"` - `"mcp-client-2025-11-20"` - `"dev-full-thinking-2025-05-14"` - `"interleaved-thinking-2025-05-14"` - `"code-execution-2025-05-22"` - `"extended-cache-ttl-2025-04-11"` - `"context-1m-2025-08-07"` - `"context-management-2025-06-27"` - `"model-context-window-exceeded-2025-08-26"` - `"skills-2025-10-02"` - `"fast-mode-2026-02-01"` - `"output-300k-2026-03-24"` - `"user-profiles-2026-03-24"` - `"user-profiles-2026-08-18"` - `"user-profiles-2026-09-04"` - `"advisor-tool-2026-03-01"` - `"managed-agents-2026-04-01"` - `"cache-diagnosis-2026-04-07"` - `"dreaming-2026-04-21"` - `"thinking-token-count-2026-05-13"` - `"server-side-fallback-2026-06-01"` - `"server-side-fallback-2026-07-01"` - `"fallback-credit-2026-06-01"` - `"fallback-credit-2026-07-01"` - `"agent-memory-2026-07-22"` - `"mid-conversation-tool-changes-2026-07-01"` - `"compact-2026-01-12"` - `"computer-use-2025-11-24"` - `"mcp-tunnels-2026-06-22"` - `"structured-outputs-2025-11-13"` - `"task-budgets-2026-03-13"` - `"thinking-display-updates-2026-08-18"` - `"ce-user-management-2026-07-13"` - `"mid-conversation-output-config-2026-07-01"` - `"thinking-binding-controls-2026-08-01"` - `"mid-conversation-system-clear-at-2026-08-21"` - `"compact-2026-09-04"` - `"inline-tools-2026-09-15"` - `"mcp-client-2026-09-15"` - `"ce-plugins-2026-09-01"` - `"spend-limit-reads-2026-09-26"` - `workspace_id: Optional[str]` (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 - `type BetaManagedAgentsMemoryListItem = ...` One item in a [List memories](https://platform.claude.com/docs/en/api/beta/memory_stores/memories/list?sdk_languages=python) 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: Literal["memory"]` - `id: str` 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: str` 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: int` Size of `content` in bytes (the UTF-8 plaintext length). Always populated, regardless of `view`. format: int32 - `created_at: datetime` When this memory was created, in RFC 3339 format. format: date-time - `memory_store_id: str` ID of the memory store this memory belongs to (a `memstore_...` value). - `memory_version_id: str` 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=python). - `path: str` 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: datetime` 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=python). format: date-time - `content: Optional[str]` 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=python) 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: Literal["memory_prefix"]` - `path: str` 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 ```python import os from anthropic import Anthropic client = Anthropic( api_key=os.environ.get( "ANTHROPIC_API_KEY" ), # This is the default and can be omitted ) page = client.beta.memory_stores.memories.list( memory_store_id="memory_store_id", ) page = page.data[0] print(page) ``` ### 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=" } ```
