# Retrieve a Memory

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

Retrieve a Memory

## Path parameters

- `memory_store_id: string`

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

- `memory_id: string`

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

## Query parameters

- `view: optional BetaManagedAgentsMemoryView`

  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.

  - `"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.

## Headers

- `"anthropic-version": optional string`

  The version of the Claude API you want to use.

  Read more about versioning and our version history [here](https://platform.claude.com/docs/en/api/versioning?sdk_languages=http).

- `"anthropic-beta": optional array of AnthropicBeta`

- `"anthropic-workspace-id": optional string`

  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

- `BetaManagedAgentsMemory object`

  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=http#view-and-edit-memories) to learn more about working with memories.

  - `type: "memory"`

  - `id: string`

    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.

  - `content_sha256: string`

    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: number`

    The size of the memory's `content` in UTF-8 bytes. It is set regardless of `view`.

    format: int32

  - `created_at: string`

    When this memory was created, in RFC 3339 format.

    format: date-time

  - `memory_store_id: string`

    ID of the memory store this memory belongs to (a `memstore_...` value).

  - `memory_version_id: string`

    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=http#audit-memory-changes) to learn more about memory versions.

  - `path: string`

    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: string`

    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

  - `content: optional string or null`

    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

```bash
curl https://api.anthropic.com/v1/memory_stores/$MEMORY_STORE_ID/memories/$MEMORY_ID \
    -H 'anthropic-version: 2023-06-01' \
    -H 'anthropic-beta: agent-memory-2026-07-22' \
    -H "X-Api-Key: $ANTHROPIC_API_KEY"
```
