Qrcode Monkey API
Overview
QRcode Monkey provides a free API to generate highly customizable QR codes with logos, custom colors, and various dot styles — far beyond the plain black-and-white output of simpler QR APIs. Developers can embed a brand logo in the center, change foreground and background colors, and choose from multiple pixel shapes through a JSON POST body, receiving a PNG image or base64 data in return. No authentication is required for the free tier.
Beginner Tip
No API key is needed for basic QR generation — send a POST request with a JSON body containing at least the "data" field (your URL or text) to get a QR code back. Start with the minimal payload {"data":"https://example.com"} and expand from there by adding "config" options like colors or a logo. The response includes a base64-encoded image you can display directly in an img tag using the data:image/png;base64 prefix.
