# Create a workspace

`POST /v1/workspaces`

Creates a workspace and the caller's owner membership atomically via `create_workspace_with_owner`. `name` is the only required field: an omitted `slug` derives from the name server-side (the canonical normalizer), an omitted `owner_name` defaults from the caller's profile display name, an omitted `owner_avatar_url` defaults from the profile photo (explicit `null` means born with no photo), and the owner member row's accent seeds from the profile's `accent_hue`. Per-user rate-limited at 5/60s (creation is heavy and abuse-sensitive). Reserved-slug rejection fires before the RPC — including for derived slugs.

## Request body

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `slug` | `string` | No | Omitted means the server derives the slug from the name via the canonical normalizer. |
| `name` | `string` | Yes |  |
| `avatar_url` | `string \| null` | No | Workspace logo URL; omitted or null means no logo. |
| `accent_hue` | `"red" \| "coral" \| "orange" \| "green" \| "teal" \| "blue" \| ...` | No | Stored monogram accent key; omitted means the tile keeps the deterministic id-hash colour. |
| `owner_name` | `string` | No | Omitted means the server defaults it from your profile display name. |
| `owner_email` | `string` | No |  |
| `owner_avatar_url` | `string \| null` | No | Omitted defaults to your profile avatar; explicit null means born with no photo. |
