QR API

A fast, stateless QR code generation API. Send it data and get back an SVG image — or the raw boolean module matrix if you want to render it yourself. Configurable error correction level, module size, and colors.

Endpoints

GET /v1/qr — generate a QR code as an SVG image (params: data, ecc, cellSize, color, bgColor)
GET /v1/qr/matrix — generate a QR code as a raw boolean module matrix (JSON), for custom rendering
GET /health — liveness check

Pricing

Free tier plus paid tiers, billed and metered through RapidAPI:

Basic — free, 500 requests/month
Pro — $4.99/month, 10,000 requests/month
Ultra — $19.99/month, 100,000 requests/month

Why QR API

Edge-deployed — runs on Cloudflare Workers, so response times don't depend on which region your users are in, unlike a single-region server behind a free QR generator like goqr.me's API or api.qrserver.com.
SVG output — crisp at any size (print, large displays, retina screens), not just a fixed-resolution PNG.
Raw-matrix output option — get the boolean module grid directly via /v1/qr/matrix if you want to render the code yourself (canvas, native UI, custom styling) instead of embedding an image.
Stateless, no logging of scanned content — the data you encode isn't persisted.
One RapidAPI key covers billing and metering — no separate account or API key management outside RapidAPI.
