Retrieve a memory

$ ant beta:memory-stores:memories retrieve
GET/v1/memory_stores/{memory_store_id}/memories/{memory_id}

Retrieve a memory

Parameters
--memory-store-id: string

Path param: Path parameter memory_store_id

--memory-id: string

Path param: Path parameter memory_id

--view: optional "basic" or "full"

Query param: Query parameter for view

--beta: optional array of AnthropicBeta

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

Returns
beta_managed_agents_memory: object{ 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.

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.

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

Size of content in bytes (the UTF-8 plaintext length). Always populated, regardless of view.

formatint32
created_at: string

A timestamp in RFC 3339 format

formatdate-time
memory_store_id: string

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

memory_version_id: 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.

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.

type: "memory"
updated_at: string

A timestamp in RFC 3339 format

formatdate-time
content: optional string

The memory's UTF-8 text content. Populated when view=full; null when view=basic. Maximum 100 kB (102,400 bytes).
