QR - API
Turn any text into a scannable QR code with one API call
QR - API이란?
qr-api generates QR codes on demand. Send a GET request with any text, get back a ready-to-use PNG — no library to install, no encoder to maintain. $10/month, unlimited requests, no rate limits. Built with Node.js, Express, Postgres, deployed on Railway with Stripe billing. This is my first project ever — went from never using git to a live paid product in two sessions, mistakes and all. Would love feedback on pricing and positioning!
