# Open a fresh draw board (browser redirect)

`GET /draw`

## Request

- Base URL: `https://cnvs.app`
- URL: `https://cnvs.app/draw`
- Auth: none declared

Human-friendly entry point for sharing a new draw board. Creates a fresh board in `draw` mode and responds with `302 Found` to `https://cnvs.app/#<id>` — a clean URL you can paste into chat. Optional query `seed` (`mermaid-flowchart` / `mermaid-mindmap`) pre-populates the canvas with an example Mermaid diagram; an absent or unknown `seed` yields a plain blank draw board.

Shares the `POST /api/boards` per-IP create cap (5 / 60s per `CF-Connecting-IP`).

## Query parameters

- `seed` 'mermaid-flowchart' | 'mermaid-mindmap'

## Other responses

- `302`: Redirect to the new board at `/#<id>`.
- `429`: Rate limit exceeded. Standard REST/MCP: 60 requests/10s/board; valid X-Import-Token infrastructure tier: 600/10s/board; browser WebSocket always 60/10s/board. REST/MCP enforcement is soft per-isolate; WebSocket enforcement is strong per Durable Object.
