One GET. No auth. No watermark.
You're building a feature that needs to generate QR codes — for a ticketing system, a logistics tool, an internal dashboard, anywhere. You don't want to ship a 100KB QR library inside your client bundle, deal with signup flows, or run into watermark surprises in production.
QRThis exposes a public REST API. Send a single GET request with the URL you want encoded, get back a PNG or SVG image. No API key, no signup, no rate-limit traps. Drop it into an <img> tag from any origin. CORS is open. Costs nothing.
