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.

Security Scan

The skill is internally consistent for generating QR codes via the AceToolz API; it only sends the provided content to the AceToolz endpoint and does not request unrelated credentials or local files.

Purpose & Capability

Name/description match the runtime instructions: the skill calls AceToolz's QR generator API and returns hosted image URLs. Nothing requested (no env vars, no binaries) is disproportionate to this purpose.

Instruction Scope

SKILL.md directs the agent to run curl/Invoke-RestMethod to POST user-provided content to https://www.acetoolz.com/api/openclaw/qr-generator. It does not read local files or other environment variables. Note: user content is transmitted to a third-party service (AceToolz), which is expected for this skill but relevant for privacy.

Install Mechanism

Instruction-only skill with no install spec and no code files — lowest install risk. It relies on existing system tooling (curl/PowerShell) which is normal.

Credentials

No environment variables, secrets, or config paths are requested. The skill does not ask for unrelated credentials or elevated access.

Persistence & Privilege

always is false and autonomous invocation is allowed (platform default). The skill does not request permanent/overbroad privileges or modify agent/global configuration.

Assessment

This skill will send whatever text or URL you provide to AceToolz's API and return a hosted image URL. Do not use it to encode sensitive secrets or private data unless you're comfortable that a third party will receive and host that content. Be aware of the documented rate limit (30 requests/min) and that hosted QR images may be publicly accessible. If you need local-only QR generation or stricter privacy, consider a local tool/library instead of this skill.

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.
