Workspace Management Create, configure, and manage workspaces within organizations. Control members, assets, shares, and AI intelligence settings.

Base URL: https://api.fast.io/current/ Auth: Bearer {jwt_token} IDs: 20-digit numeric strings

Workspaces are shared project spaces within an organization. They support file versioning, search, AI chat, and member management. Most workspace endpoints also accept the workspace's folder_name (e.g., my-project) in place of the numeric ID.

Field Constraints

Field	Constraint
`folder_name`	Regex `^[\p{L}\p{N}-]+$` (letters, numbers, hyphens). Must be globally unique.
`name`	2–100 characters, string
`description`	10–1000 characters, string (optional)
`title` (shares)	2–80 characters
`custom_name` (shares)	10–100 characters, URL-friendly

Permission Values

`perm_join` — who can self-join from the parent org

Value	Description
`'Member or above'`	Any org member can join (default)
`'Admin or above'`	Only org admins and owners
`'Only Org Owners'`	Only org owners

`perm_member_manage` — who can manage workspace members

Value	Description
`'Member or above'`	Any workspace member can manage (default)
`'Admin or above'`	Only workspace admins and owners

Permission Levels (numeric hierarchy)

Level	Numeric	Description
Owner	1000	Full control; one per workspace
Admin	500	Administrative access
Member	100	Standard member
Guest	50	Limited guest access
View	20	Read-only access

Intelligence Setting

The intelligence boolean on a workspace controls whether uploaded files are automatically indexed for RAG (retrieval-augmented generation).

Enable (intelligence=true, default for agent accounts) — files are auto-indexed for semantic search, summarization, and citation. Required for chat_with_files AI chat type.
Disable (intelligence=false) — files are stored/shared without RAG indexing. You can still attach files directly to a chat type conversation for one-off analysis.
Set at creation: POST /current/org/{org_id}/create/workspace/ with intelligence=true|false
Update later: POST /current/workspace/{id}/update/ with intelligence=true|false
Cannot be re-enabled once disabled. Attempting to set intelligence=true after it was set to false returns an error.
