How this service works
Encode text, a URL or a payment string as a QR code, returned as SVG, a base64 PNG, or the raw module matrix.
Output
Returns the QR code in the requested format: an SVG string, a base64-encoded PNG image, or a 2D boolean module matrix representing the QR code grid. The output encodes the provided text payload at the specified scale and error correction level.
Example use cases
QR code for a restaurant menu
“Make a QR code SVG for https://menusite.com/bistro-du-coin that I can put on table tents — use scale 8 and medium error correction.”
Payment string QR for crypto checkout
“Encode this Lightning payment string as a QR code PNG at scale 6 with high error correction: lnbc500n1p3zkhp3pp5xyz...”
Raw matrix for custom QR renderer
“Give me the raw module matrix for the text 'Hello, World!' with low error correction so I can render it myself in my app.”

Choose this endpoint when you need a quick, hosted QR code generation service that supports multiple output formats (SVG, PNG, matrix) and is accessible via a paid API with per-call pricing. It is especially useful when integrating QR codes into automated agent workflows, payment flows (Lightning/crypto URIs), or when you need the raw module matrix for custom rendering pipelines.
