How this service works
MCP server with 49 developer tools + 300+ REST APIs — agent memory, QR codes, passwords, AI text, finance, health, crypto, weather, and more. Free tier, no API key needed.
Output
Returns a QR code image (or a confirmation of generation) encoded in the requested format (e.g. PNG), containing the encoded input text with the specified visual styling including foreground color, background color, and size.
Example use cases
Business card QR code
“Create a QR code for my LinkedIn profile at https://linkedin.com/in/janedoe — make it 250px, black on white, PNG format, with high error correction so it still scans even if slightly damaged.”
WiFi network sharing QR
“Generate a QR code for the text 'WIFI:S:MyHomeNetwork;T:WPA;P:supersecret;;' in a 400px PNG with a light gray background and dark green foreground, medium error correction.”
Event flyer QR code
“Make a QR code pointing to https://eventbrite.com/myevent in 500px size with a bold red color on a white background and high error correction — I want to print it on a poster so it needs to be big and reliable.”
