Emblem
QR codes as an API

Generate QR codes
with one API call.

Emblem turns any text or URL into a crisp QR code — sized, coloured, and formatted to your spec. Grab a key and hit one endpoint.

GET /v1/qr?data=…&dark=818cf8

One clean endpoint

GET /v1/qr with size, colours, margin, error-correction, and PNG or SVG output.

API keys, done right

Generate and revoke keys; they're sha-256 hashed at rest and shown exactly once.

Usage & rate limits

Every request is metered. A daily limit protects the free tier, with headers to track it.

Copy-paste docs

cURL and JS examples plus a params reference — you'll be generating codes in a minute.
