List memories

client.beta.memoryStores.memories.list(memoryStoreID, params?, options?): PageCursor<BetaManagedAgentsMemoryListItem>
GET/v1/memory_stores/{memory_store_id}/memories

List memories

Parameters
memoryStoreID: string
params: MemoryListParams { depth, limit, page, 3 more }
depth?: number

Query param: 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.

formatint32
limit?: number

Query param: 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.

formatint32
page?: string

Query param: 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?: string

Query param: 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

Query param: 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.

One of the following:
"basic"
"full"
betas?: Array<AnthropicBeta>

Header param: Optional header to specify the beta version(s) you want to use.

One of the following:

Returns
BetaManagedAgentsMemoryListItem = BetaManagedAgentsMemory { id, content_sha256, content_size_bytes, 7 more } | BetaManagedAgentsMemoryPrefix { path, type }

One item in a List memories response: either a memory object or, when depth is set, a memory_prefix rollup marker.

One of the following:
BetaManagedAgentsMemory { id, content_sha256, content_size_bytes, 7 more }

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.

BetaManagedAgentsMemoryPrefix { path, type }

A rolled-up directory marker returned by List memories 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: 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.
