AceToolz QR Code Generator

Generate QR codes for any URL or text instantly using AceToolz. Returns a hosted image URL ready to share in chat.

Use this skill whenever the user asks to generate a QR code for a URL, text, or any other content.

How to Use

Use exec to call the AceToolz API. Detect the OS and run the appropriate command:

Windows (PowerShell):

Invoke-RestMethod -Uri "https://www.acetoolz.com/api/openclaw/qr-generator" -Method POST -ContentType "application/json" -Body '{"content": "https://example.com", "size": 300}'

macOS / Linux (curl):

curl -s -X POST https://www.acetoolz.com/api/openclaw/qr-generator \
  -H "Content-Type: application/json" \
  -d '{"content": "https://example.com", "size": 300}'

Adjust the content and size parameters based on the user's request.

Parameters

Field	Type	Required	Description
content	string	Yes	The URL or text to encode in the QR code (max 2,000 chars)
size	number	No	QR image size in pixels (100–500, default 300)

Response

The API returns two image fields:

• qr_image_url — a direct hosted image URL (share this in chat — works in WhatsApp, Telegram, Slack, etc.)
• qr_data_url — a base64-encoded PNG data URL (for platforms that support it)

Presenting Results

Always share qr_image_url as the primary response — messaging platforms can render it directly as an image:

Here is your QR code for: https://example.com [image: qr_image_url]

Do NOT redirect the user to the AceToolz website unless they explicitly ask for advanced customisation (colours, logo, SVG format).

Error Handling

• If content is missing, ask the user what they want encoded in the QR code.
• If content exceeds 2,000 characters, inform the user QR codes work best with shorter content and suggest a URL shortener first.
• If the API returns 429, the limit is 30 requests/minute.
• If the API is unreachable, tell the user and suggest visiting https://www.acetoolz.com/generate/tools/qr-generator directly.
