# List Workspace Facts

> Returns facts across projects and actors in a workspace

```
GET /openapi/memorylake/api/v3/workspaces/{workspaceId}/memories/facts
```

Returns facts across the given projects and/or actors in a workspace, newest first. Each fact is annotated with the project or actor it belongs to, so you can query knowledge workspace-wide without calling each project or actor endpoint separately.

At least one `project_ids` or `actor_ids` entry is required, and the two combined must reference at most 50 distinct projects/actors.

<Note>
  **Permission required:** `project:mem_list`
</Note>

</ParamField>

<ParamField query="fact_fuzzy" type="string">
