How this service works

Generate a styled QR code PNG (base64 in JSON): custom foreground/background hex colours, module size, border, and error-correction level.

Output

A JSON object containing a base64-encoded PNG of the styled QR code. The image reflects all specified parameters: foreground and background colors, pixels-per-module size, quiet-zone border width, and the chosen error-correction level. The base64 string can be decoded and rendered or embedded directly in HTML as a data URI.

Example use cases

Branded QR code for product packaging

“Generate a QR code for https://acmebeverages.com/promo with our brand colors — dark green foreground (#1a5c2a) on a white background (#ffffff), 15 pixels per module, border of 3, and Q error correction so it scans reliably even if slightly worn.”

Event poster QR code with large modules

“Create a high-visibility QR code for https://eventbrite.com/e/summer-gala-2025 to print on a large poster — use 30 pixels per module, black on yellow (#ffdd00), a 5-module border, and H error correction.”

Minimal contact card QR code

“Make a compact QR code encoding 'BEGIN:VCARD\nFN:Jane Doe\nTEL:5551234567\nEND:VCARD' with a 1-module border, 8 pixels per module, black on white, and M error correction for a business card.”

When to prefer

Choose this endpoint when you need a visually branded or customized QR code — specific hex colors, non-default module size, or a particular error-correction level. Use the plain sibling endpoint for quick black-on-white defaults. Use the batch sibling endpoint when generating multiple QR codes at once. This endpoint is ideal when the QR code must match brand guidelines or be printed at a specific scale.

Side effects

Unsupported error_correction value (not L/M/Q/H) returns a 400 error
Payment not included or insufficient USDC triggers a 402 response
Empty or missing 'data' field returns a 400 error
