# Remove an AI Studio group member

`DELETE /api/svc-registry/group-memberships/{group_id}`

## Request

- Base URL: `https://app.gocrisp.com` (the document declares no server; this is the origin it was published from)
- URL: `https://app.gocrisp.com/api/svc-registry/group-memberships/{group_id}`
- Auth: none declared

Remove one direct membership, without modifying org links or grants.

Requires the configured Studio caller. Autonomous Terraform needs no group
FGA grant; runtime must forward a user.
User ids are Auth0 subjects, service-account ids are Dock ids or gcpsa segments,
and nested-group ids are exact FGA ids. An optional matching kind: prefix is
normalized before dispatch. Readonly/deleted groups cannot be edited.
With X-User-Authorization, require selected-scope Studio workspace owner and
the live group/organization boundary. Service grants cannot replace that user.

## Path parameters

- `group_id` string, required

## Query parameters

- `kind` 'user' | 'service_account' | 'group', required
