Is the QRKit Tools QR code API free?
Yes. The API is free and needs no API key, no account and no registration. Send a request to https://qrkit.tools/api/qr and you get an image back.
Do I need an API key?
No. There is no key, token or header to send. The endpoint is public and CORS is open, so it works from a browser, a server or an <img> tag.
What formats can the API return?
PNG by default, or SVG with format=svg. Set download=1 to have the image returned as a file download instead of inline.
How large can the encoded data be?
Up to 2048 characters in the data parameter, and up to 1024 pixels for the size parameter.
Can I use the API in production?
Yes, and it is free to do so. It is a best-effort public endpoint with no uptime guarantee, so cache the generated images on your side rather than requesting the same code on every page view.
Does the API store the data I encode?
The endpoint renders the image from the request and returns it. Encoded content is not exposed in any public listing and never appears in product analytics.
