No reprint

Change the destination with a PATCH

Print once. Point scanners somewhere new whenever the product, campaign, or store listing changes — without touching the physical code.

PATCH /v1/qr/qr_...
{ "targetUrl": "https://new.example.com" }

Edge rules

One QR code. Many destinations at the edge.

Scans resolve at the edge by device, country, time, or weighted A/B (weights sum to 100) — first match wins, then your default destination. Any plan can add a password gate before the redirect. Change rules anytime without reprinting.

Order: device → country → time → A/B → destination.

POST /v1/qr
{
  "targetUrl": "https://example.com",
  "rules": {
    "device": {
      "ios": "https://apps.apple.com/…",
      "android": "https://play.google.com/…"
    }
  }
}

One API spine for most dynamic QR jobs

Compose mint through brand in code — instead of bolting a generator to a redirect service and hoping it holds.

Why not just use node-qrcode?

Generating a PNG is easy. Owning mint, print, live links, routing, and scan events at scale is the real product — that is what QR. ships as an API.

Minutes, not weeks

SDKs for the stack you already ship

Grab an API key, install an official client (Node, Python, Go, PHP, Ruby) or call REST from any language (C#, Java, .NET, …), and create your first dynamic QR before standup ends. CLI for scripts — OpenAPI when you need a generated client.
