Returns
data: optional array of BetaManagedAgentsMemoryVersion { id, created_at, memory_id, 10 more }

One page of memory_version objects, ordered by created_at descending (newest first), with id as tiebreak.

id: string

Unique identifier for this version (a memver_... value).

created_at: string

A timestamp in RFC 3339 format

formatdate-time
memory_id: string

ID of the memory this version snapshots (a mem_... value). Remains valid after the memory is deleted; pass it as memory_id to List memory versions to retrieve the memory's retained versions, including the deleted row while the lineage is retained.

memory_store_id: string

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

operation: BetaManagedAgentsMemoryVersionOperation

The kind of mutation a memory_version records. Every non-no-op mutation to a memory appends exactly one version row with one of these values.

One of the following:
"created"
"modified"
"deleted"
type: "memory_version"
content: optional string or null

The memory's UTF-8 text content as of this version. null when view=basic, when operation is deleted, or when redacted_at is set.

content_sha256: optional string or null

Lowercase hex SHA-256 digest of content as of this version (64 characters). null when redacted_at is set or operation is deleted. Populated regardless of view otherwise.

content_size_bytes: optional number or null

Size of content in bytes as of this version. null when redacted_at is set or operation is deleted. Populated regardless of view otherwise.

formatint32
created_by: optional BetaManagedAgentsActor

Identifies who performed a write or redact operation. Captured at write time on the memory_version row. The API key that created a session is not recorded on agent writes; attribution answers who made the write, not who is ultimately responsible. Look up session provenance separately via the Sessions API.

One of the following:
path: optional string or null

The memory's path at the time of this write. null if and only if redacted_at is set.

redacted_at: optional string or null

A timestamp in RFC 3339 format

formatdate-time
redacted_by: optional BetaManagedAgentsActor

Identifies who performed a write or redact operation. Captured at write time on the memory_version row. The API key that created a session is not recorded on agent writes; attribution answers who made the write, not who is ultimately responsible. Look up session provenance separately via the Sessions API.

One of the following:
next_page: optional string or null

Opaque cursor for the next page (a page_... value), or null if there are no more results. Pass as page on the next request.
