How this service works
Encode text or a URL as a QR code: PNG (base64 and a data URL) or SVG, with the size and error correction level you choose.
Output
A JSON object containing: the image format used (png or svg), the rendered image as base64-encoded PNG (png_base64) and as a ready-to-use data URL (data_url), the size in pixels, and the byte size of the image. For SVG format, the response contains the SVG markup accordingly.
Example use cases
QR code for event landing page
“Make a QR code for https://events.mycompany.com/summit2025 — 400 pixels, PNG format, medium error correction — I want to embed it in the event poster.”
Business card URL QR code
“Generate a compact 200-pixel QR code for my LinkedIn profile at https://linkedin.com/in/janedoe — SVG format so it scales cleanly when printed on my business cards.”
Offline wifi password sharing
“Encode the text WIFI:S:HomeNetwork;T:WPA;P:mysecretpassword;; as a QR code at 300 pixels with H error correction level so guests can scan it even if the printout is a bit crumpled.”
Technical details
Endpoint
GEThttps://web.kagurazaka.dev/v1/qr?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a programmatic, pay-per-call QR code generator that returns machine-usable base64 or SVG output (not just a rendered web image), supports configurable size and ISO error correction levels (L/M/Q/H), and fits into an x402 micropayment workflow. Prefer it over browser-based QR generators when the output needs to be embedded inline in HTML, PDF, or other documents.
Side effects
- text parameter missing — returns error requiring the text query param
- text exceeds 2000 characters — returns error or truncation
- size out of range (below 64 or above 1024) — returns validation error
- invalid level enum value — returns bad request
- payment not provided or invalid — returns HTTP 402 requiring x402 payment
