Public embed info — branding and enabled toggles. No authentication required; safe to call from an anonymous browser.

{
  "enabled": true,
  "brandTitle": "Acme Studio",
  "brandIconUrl": "https://.../icon.png",
  "brandAccentColor": "#FB923C",
  "downloadsEnabled": true,
  "assetPickerEnabled": false,
  "smartResizeEnabled": true,
  "allowedDomains": ["app.example.com"]
}

Mint a short-lived embed session bearer token. The embed page calls this itself when it loads; every visitor gets the same access to the workspace's templates.

  "token": "femb_...",
  "expiresIn": 3600,
  "config": {
    "enabled": true,
    "brandTitle": "Acme Studio",
    "brandIconUrl": "https://.../icon.png",
    "brandAccentColor": "#FB923C",
    "downloadsEnabled": true,
    "assetPickerEnabled": false,
    "smartResizeEnabled": true,
    "allowedDomains": ["app.example.com"]
  }
}

List the workspace's templates. Every visitor of the embed sees the same list.

Create a template in the workspace, shared with every visitor. Sends the template.created webhook.

The editable design document, for the embedded studio to open.

Save the design document (embedded editor autosave). One template.updated webhook follows once the editing goes quiet.

Tell BuildOnce the embedded studio was closed. A template.updated webhook normally waits until autosaving goes quiet for 2 minutes — this sends it at once instead, so the host doesn't have to wait on a user who just left.

Rasterize the current draft. Gated by the embed's Downloads toggle — a session without downloadsEnabled won't hold the render:write scope needed here. A video (mp4, webm, gif) answers 202 { renderId, status } while it draws; an image answers in full.

A render's status after a 202: queued, processing, succeeded (with its files) or failed. Gated by the Downloads toggle.
