Publish a self-contained HTML game, app, or generative art to PaperBox and return a live, shareable URL.

Endpoint (confirmed working)

POST https://paperbox-beta.vercel.app/api/games

Workflow

Ensure the HTML is complete and self-contained (all CSS/JS inlined).
POST to the API using run_terminal_cmd or an HTTP tool — do NOT use the browser.
Parse the JSON response and extract data.shareableUrl.
Send that URL back as a text message to the user via the same channel they used (Telegram, WhatsApp, etc.). Do not open any browser or navigate anywhere.

Request

curl -X POST https://paperbox-beta.vercel.app/api/games \
  -H "Content-Type: application/json" \
  -H "X-API-Key: <from openclaw.json skills.entries.paperbox.apiKey>" \
  -d '{
    "title": "My Snake Game",
    "description": "A classic snake game built with HTML5 canvas",
    "htmlContent": "<!DOCTYPE html><html>...</html>"
  }'

Response (success)

{
  "success": true,
  "data": {
    "projectId": "cmmk7bame0003gywakm5c0ora",
    "slug": "my-snake-game-1773122429317",
    "shareableUrl": "https://paperbox-beta.vercel.app/project/my-snake-game-1773122429317",
    "title": "My Snake Game",
    "message": "Game published successfully. Share this link with others."
  }
}

The shareable link is at data.shareableUrl — use this exact value. Do not construct the URL manually from the slug.
