}Restore a memory revision
Requires memory:write. Restores one file using its exact history path and revision id through the existing memory service. Personal scope is caller-only and available only in legacy workspaces; team scope requires an owner or admin, checked in the write transaction. A foreign scope, owner, path or missing revision returns 404 memory_revision_not_found. A deletion revision retains the deleted text and restores it. This is an unconditional restore, not an expected-revision write; unsupported body fields are rejected. History is preserved and the restore is itself a new revision. restored=false means the selected text is already current.

}Authorizations
Your Reason API key from Settings › API keys. New keys use reason_; legacy ara_ keys remain accepted. Keys are capability-scoped: run, mcp:read, mcp:write, secrets:read, secrets:write, sessions:read, sessions:debug, knowledge:read, memory:read, memory:write, skills:read, skills:write, repos:read, repos:write, reviews:read, reviews:write, deployment:read, analytics:read, org:read, org:write, attachments:read, attachments:write, guardrails:read, guardrails:write, network:read, network:write, automations:read, automations:write, agent_auth:read. network:read and network:write are opt-in, excluded from default keys. network:read reads the saved workspace network policy; network:write replaces custom allowed hosts and requires a current organization owner/admin. Legacy project PATCH requests containing network_allowed_hosts also require network:write plus their existing run scope and project management permission; saved project hosts do not affect current session egress. Only owners/admins can mint or manage keys with network:write; keys cannot grant themselves more authority. See /docs/network-policies for replacement semantics and runtime applicability. mcp:write manages MCP server configuration only; it does not authorize remote MCP-tool execution. sessions:read reads sessions, including the assistant, reasoning and tool activity in their events. sessions:debug is privileged: only for organization owners/admins, it expands session events to the full diagnostic projection (diagnostic event kinds, status text and raw event metadata).
Path Parameters
Organization id or slug. Resolve it with GET /v3/self.
Body
team: the Workspace's shared memory. Legacy workspaces also support personal; consolidated workspace resources return workspace_memory_scope_required for personal scope.
personal, team The exact path returned by listMemoryHistory for the revision to restore.
The history change's id, not an expected current revision. Restoring replaces current text unconditionally.

Restore result.
team: the Workspace's shared memory. Legacy workspaces also support personal; consolidated workspace resources return workspace_memory_scope_required for personal scope.
personal, team False when the file already holds the selected revision's text. A true restore creates a new revision; it never rewrites history.
