How this service works
A QR code for a text of up to 300 characters (a URL, Wi-Fi login or contact card), generated locally. format=svg returns the image itself as image/svg+xml; format=json returns the version, the module count, the SVG and a data URI. Error correction L, M, Q or H (default M); size from 128 to 1024 pixels (default 512).
Output
Returns a JSON object containing the SVG markup of the QR code, a base64-encoded data URI for direct embedding in HTML or apps, the original text, the QR version number, module count, error correction level used, and a checkedAt timestamp.
Example use cases
QR code for a product landing page
“Create a QR code for https://acmecorp.com/promo — 512 pixels, SVG output, medium error correction, so I can drop it on a flyer.”
High-durability QR for printed merchandise
“Make me a QR code for https://myband.com/merch using H error correction and 1024 pixels — it needs to survive some wear and tear when printed on t-shirts.”
QR code for plain text Wi-Fi instructions
“Generate a QR code that encodes the text 'WIFI:T:WPA;S:GuestNetwork;P:welcome123;;' in SVG format at 512 pixels with Q error correction.”

Endpoint
GEThttps://api.sitecheck-api.workers.dev/api/qr?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call QR code generator with no signup, returning SVG or JSON with a data URI suitable for direct embedding. Ideal for agents that need to generate QR codes on demand during workflows (e.g. adding a QR to a generated document or email) without standing up a dedicated QR service.
Side effects

- Size outside 128–1024 pixel range — error returned
- Missing required 'text' query parameter — 400 error
- Invalid format value (must be svg or json) — error returned
