GET /v1/memory_stores/{memory_store_id}/memory_versions

List memory versions

Path parameters

  • memory_store_id: string

The ID of the memory store whose version history to list (memstore_...).

Query parameters

  • api_key_id: optional string

Return only versions written with the API key that has this ID.

  • "created_at[gte]": optional string

Return versions created at or after this time (inclusive).

format: date-time

  • "created_at[lte]": optional string

Return versions created at or before this time (inclusive).

format: date-time

  • limit: optional number

The maximum number of versions to return per page. Defaults to 20.

format: int32

  • memory_id: optional string

Return only versions of the memory with this ID (mem_...).

The filter still works after the memory is deleted. The results then include the version whose operation is deleted.

  • operation: optional BetaManagedAgentsMemoryVersionOperation

Return only versions that record this kind of change.

  • "created"

The memory was created. The first version in any memory's lineage.

  • "modified"

The memory's content, path, or both were changed via update. Writes the agent makes through the filesystem mount also appear as modified.

  • "deleted"

The memory was deleted. The content, content_size_bytes, and content_sha256 fields are null on this version. The preceding version, while it is retained, records the deleted content's size and hash.

  • page: optional string

The next_page value from a previous response, to get the next page. Omit it to get the first page.

  • service_account_id: optional string

Return only versions written by the service account with this ID (svac_...).

  • session_id: optional string

Return only versions written by the session with this ID.

  • view: optional BetaManagedAgentsMemoryView

Selects which projection of a memory or memory_version the server returns. basic returns the object with content set to null; full populates content. When omitted, the default is endpoint-specific: retrieve operations default to full; list, create, and update operations default to basic. Listing with view=full caps limit at 20.

  • "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.

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

  • data: optional array of BetaManagedAgentsMemoryVersion

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

  • type: "memory_version"
  • id: string

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

  • created_at: string

When this version was written, in RFC 3339 format.

format: date-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 this version records: created, modified, or deleted.

  • "created"

The memory was created. The first version in any memory's lineage.

  • "modified"

The memory's content, path, or both were changed via update. Writes the agent makes through the filesystem mount also appear as modified.

  • "deleted"

The memory was deleted. The content, content_size_bytes, and content_sha256 fields are null on this version. The preceding version, while it is retained, records the deleted content's size and hash.

  • 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.

format: int32

  • created_by: optional BetaManagedAgentsActor

Who performed this write: one of session_actor, api_actor, user_actor, or service_account_actor; null when no writer is recorded. Captured at write time and preserved through redaction. A session_actor is an agent writing through the store's mounted filesystem at /mnt/memory/. The API key that created that session is not recorded on agent writes, so attribution names who made the write, not who is ultimately responsible; look up session provenance via the Sessions API.

  • BetaManagedAgentsSessionActor object

An agent acting during a session, for example through the session's mounted filesystem. It names the session itself, not the user or API key that started the session.

  • type: "session_actor"
  • session_id: string

ID of the session (a sesn_... value). Look up the session via Retrieve a session for further provenance.

minLength: 1

  • BetaManagedAgentsAPIActor object

A direct caller of the public API, identified by the API key that authenticated the request.

  • type: "api_actor"
  • api_key_id: string

ID of the API key (an apikey_... value). This identifies the key, not the secret.

minLength: 1

  • BetaManagedAgentsUserActor object

A human user, for example acting through the Juglow Console.

  • type: "user_actor"
  • user_id: string

ID of the user (a user_... value).

minLength: 1

  • BetaManagedAgentsServiceAccountActor object

A workload authenticated as a service account, for example via Workload Identity Federation.

  • type: "service_account_actor"
  • service_account_id: string

ID of the service account (a svac_... value).

minLength: 1

  • 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

When this version was redacted, in RFC 3339 format, or null if it has not been redacted. When set, content, path, content_size_bytes, and content_sha256 are all null. See Redact a memory version.

format: date-time

  • redacted_by: optional BetaManagedAgentsActor

Who redacted this version, or null if it has not been redacted. In practice always an api_actor, user_actor, or service_account_actor (agents do not have a redact capability).

  • 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.
