# Retrieve a Memory

`BetaManagedAgentsMemory Beta.MemoryStores.Memories.Retrieve(parameters, cancellationToken = default)`

**GET** `/v1/memory_stores/{memory_store_id}/memories/{memory_id}`

Retrieve a Memory

## Parameters

- `MemoryRetrieveParams parameters`

  - `required string memoryStoreID` (path parameter)

    The ID of the memory store that holds the memory (`memstore_...`).

  - `required string memoryID` (path parameter)

    The ID of the memory to retrieve (`mem_...`).

  - `BetaManagedAgentsMemoryView view` (query parameter)

    Whether a `memory` or `memory_version` in the response includes its `content`. Defaults to `full` on retrieve operations and to `basic` on list, create, and update operations.

    With `full`, list operations return at most 20 items per page.

  - `IReadOnlyList<AnthropicBeta> 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.

  - `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 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).

## Example

```csharp
using System;
using Anthropic.Models.Beta.MemoryStores.Memories;

MemoryRetrieveParams parameters = new()
{
    MemoryStoreID = "memory_store_id",
    MemoryID = "memory_id",
};

var betaManagedAgentsMemory = await client.Beta.MemoryStores.Memories.Retrieve(parameters);

Console.WriteLine(betaManagedAgentsMemory);
```
