--- title: List memories url: https://platform.claude.com/docs/en/api/go/beta/memory_stores/memories/list --- # List memories `client.Beta.MemoryStores.Memories.List(ctx, memoryStoreID, params) (*PageCursor[BetaManagedAgentsMemoryListItemUnion], error)` **GET** `/v1/memory_stores/{memory_store_id}/memories` List memories ## Parameters - `memoryStoreID string` (path parameter) The ID of the memory store to list memories from (`memstore_...`). - `params BetaMemoryStoreMemoryListParams` - `Depth param.Opt[int64] Optional` (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 param.Opt[int64] Optional` (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 param.Opt[string] Optional` (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. - `PathPrefix param.Opt[string] Optional` (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 BetaManagedAgentsMemoryView Optional` (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. - `Betas []AnthropicBeta Optional` (header parameter) This endpoint is in beta: requests must send `agent-memory-2026-07-22` or `managed-agents-2026-04-01` in this header. -

`WorkspaceID param.Opt[string] Optional` (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 BetaManagedAgentsMemoryListItemUnion interface{…}` One item in a [List memories](https://platform.claude.com/docs/en/api/beta/memory_stores/memories/list?sdk_languages=go) response: either a `memory` object or, when `depth` is set, a `memory_prefix` rollup marker. - `type 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 BetaManagedAgentsMemoryType` - `ID string` Unique identifier for this memory (a `mem_...` value). Stable across renames; use this ID, not the path, to read, update, or delete the memory. - `ContentSha256 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`. - `ContentSizeBytes int64` Size of `content` in bytes (the UTF-8 plaintext length). Always populated, regardless of `view`. format: int32 - `CreatedAt Time` When this memory was created, in RFC 3339 format. format: date-time - `MemoryStoreID string` ID of the memory store this memory belongs to (a `memstore_...` value). - `MemoryVersionID string` 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=go). - `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. - `UpdatedAt Time` 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=go). format: date-time - `Content string Optional` The memory's UTF-8 text content. Populated when `view=full`; `null` when `view=basic`. Maximum 100 kB (102,400 bytes). - `type BetaManagedAgentsMemoryPrefix` A rolled-up directory marker returned by [List memories](https://platform.claude.com/docs/en/api/beta/memory_stores/memories/list?sdk_languages=go) 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 BetaManagedAgentsMemoryPrefixType` - `Path string` 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 ```go package main import ( "context" "fmt" "github.com/anthropics/anthropic-sdk-go" "github.com/anthropics/anthropic-sdk-go/option" ) func main() { client := anthropic.NewClient( option.WithAPIKey("my-anthropic-api-key"), ) page, err := client.Beta.MemoryStores.Memories.List( context.TODO(), "memory_store_id", anthropic.BetaMemoryStoreMemoryListParams{}, ) if err != nil { panic(err.Error()) } fmt.Printf("%+v\n", 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=" } ```
