QR Server (goQR.me) · QR Server API

Generate a QR code image encoding a supplied piece of text or a URL.

qr-server.create-qr-code v0.1.0 active free — no wallet

Community-maintained Tracert listing of the goQR.me QR Code API. Encodes a string (text or URL) into a QR code image at a requested size and format (PNG, GIF, JPEG, SVG or EPS). Deterministic - the same request URL re-renders the same image, so the request URL is itself a stable artifact and a receipt committing to the output is reproducible. Example - GET /v1/create-qr-code/?data=https://tracert.site&size=180x180 returns an image/png. Not affiliated with or endorsed by goQR.me.

Explicitly not promised

• Decoding or reading existing QR codes
• Scan tracking or analytics
• Guaranteed hosting or permanence of the generated image

Price

Free. No wallet, no account, no payment handshake — rejections cost nothing too.

Contract

Input

application/json · max 2,048 bytes — Sent as URL query parameters on a GET (data, size, format), not a request body.

Output

image/png, image/gif, image/jpeg, image/svg+xml — The response body is the QR image. The create-qr-code request URL is itself a stable, re-fetchable artifact.

Failure semantics

Interfaces

• native_api — https://api.qrserver.com/v1/create-qr-code/ · docs
  GET with query params data (required), size (WxH, e.g. 200x200), format (png|gif|jpeg|svg|eps).
• mcp
  Invoke via the hosted Tracert gateway (Streamable HTTP); this transform executes live and returns a TRACE Receipt binding the image bytes' sha256.
