### Returns

- `BetaManagedAgentsMemoryListItem`

  One item in a [List memories](/docs/en/api/beta/memory_stores/memories/list) 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.

    - `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`.

    - `created_at: datetime`

      A timestamp in RFC 3339 format

    - `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 full history via [List memory versions](/docs/en/api/beta/memory_stores/memory_versions/list).

    - `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.

    - `type: Literal["memory"]`

      - `"memory"`

    - `updated_at: datetime`

      A timestamp in RFC 3339 format

    - `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](/docs/en/api/beta/memory_stores/memories/list) 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.

    - `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.

    - `type: Literal["memory_prefix"]`

      - `"memory_prefix"`

### 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)
```
