Question 1

What's the simplest way to generate a QR code from Python?

Accepted Answer

Two lines: `import requests; r = requests.get('https://www.qrth.is/api/generate', params={'url': 'https://example.com'}); open('qr.png','wb').write(r.content)`. That fetches the QR and saves it locally. No SDK, no API key, no auth.

Question 2

Can I generate QR codes from a Node.js or browser app?

Accepted Answer

Yes — any HTTP client works. From Node: `await fetch('https://www.qrth.is/api/generate?url=' + encodeURIComponent(myUrl))` returns a Response with the PNG bytes. From the browser, the same fetch works because we have CORS open (`Access-Control-Allow-Origin: *`).

Question 3

What about SVG output for vector pipelines?

Accepted Answer

Add `&format=svg` to the request. The response body is the SVG markup as plain text (Content-Type `image/svg+xml`). Useful for design tools (Illustrator, Figma, InDesign) or anywhere you'd want to render the QR at variable sizes without raster artifacts.

Question 4

Are there any limits on bulk programmatic generation?

Accepted Answer

Rate limit is 100 requests per IP per 24 hours. For bulk jobs above that, spread across days, use multiple IPs, or email support@qrth.is — we can raise the limit for legitimate use cases (ticketing systems, inventory management, one-time bulk print runs).
