4042 format: int32
4143
4244- `memory_id: optional string`
4345
44 Query parameter for memory_id
46 Return only versions of the memory with this ID (`mem_...`).
4547
48 The filter still works after the memory is deleted. The results then include the version whose `operation` is `deleted`.
49
4650- `operation: optional BetaManagedAgentsMemoryVersionOperation`
4751
48 Query parameter for operation
52 Return only versions that record this kind of change.

5155
56 The memory was created. The first version in any memory's lineage.
57
5258 - `"modified"`
5359
60 The memory's `content`, `path`, or both were changed via update. Writes the agent makes through the filesystem mount also appear as `modified`.
61
5462 - `"deleted"`
5563
64 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.
65
5666- `page: optional string`
5767
58 Query parameter for page

6777
6878- `view: optional BetaManagedAgentsMemoryView`
6979
70 Query parameter for view
80 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.
7181
7282 - `"basic"`
7383
84 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.
85
7486 - `"full"`
7587
88 Return the object with `content` populated. On list endpoints, `view=full` caps `limit` at 20.
