Built for Developers

Everything you need to wire QR code into your stack

A predictable REST API with the primitives real integrations need: authentication, bulk creation, dynamic destinations, analytics, and event delivery.

key

Bearer-token auth

One qrc_ key in the Authorization header. Scoped permissions for reads and writes, regenerate anytime.

Scoped keys Regenerable JSON responses

autorenew

Dynamic by default

Every QR code encodes a short link, so a PATCH to the destination re-points printed QR codes with no reprint.

Editable destinations No reprints

dynamic_feed

Bulk endpoints

Create up to 100 QR codes or short links per request, with partial-success semantics so one bad row never fails the batch.

100 per request Partial success

insights

Analytics endpoints

Pull scan and click data with country, device, daily, and referrer breakdowns, filterable by timeframe, straight into your own dashboards.

Scan & click data Timeframe filters

webhook

Scan-event webhooks

The Transform plan pushes scan events to your endpoint in real time, HMAC SHA-256 signed so you can verify every delivery.

Real-time scans HMAC signed

dns

Your own domain

Pass a verified domain_id so the short link behind each QR code uses your branded domain instead of qrch.am.

Branded domains Adapt & up

Three calls to a working integration

Create, re-point, and measure. Every response is JSON wrapped in a predictable success envelope.

Most QR code APIs sit behind a paywall

Bitly paywalls its API entirely. QR Chameleon puts a real REST API, full analytics, and dynamic QR codes on every plan, including free. See exactly how the two compare.

FAQ

Frequently Asked Questions

Yes. The REST API is included on every plan, including the free tier at 1,250 requests per month with a 60 per minute burst rate. That is enough to prototype and run small integrations without a credit card. Most competitors paywall their API entirely, so this is unusual in the QR code and link space.

Every request uses a Bearer token in the Authorization header. Your API key starts with qrc_ and is generated from your dashboard. Keys carry scoped permissions (urls:read, urls:write, qr:read, qr:write, analytics:read) and can be regenerated at any time.

Yes. Every QR code the API creates is dynamic by default. The pattern encodes a short link, so you can change the destination later, through the API or the dashboard, without regenerating or reprinting the QR code. Every scan is tracked automatically.

Yes. The POST /v1/qr/bulk endpoint creates up to 100 QR codes in a single request, with partial-success semantics so one bad row does not fail the batch. For spreadsheet-driven runs, CSV bulk upload in the dashboard handles up to 3,000 QR codes per file on the Transform plan.

Monthly request caps and burst rates scale by plan: Free is 1,250 per month at 60 per minute, Blend is 6,500 at 120 per minute, Adapt is 30,000 at 300 per minute, and Transform is 250,000 at 1,200 per minute. Enterprise custom arrangements remove the monthly cap entirely.

Yes. Dedicated analytics endpoints return scan and click data with country, device, daily, and referrer breakdowns, filterable by timeframe. The Transform plan also delivers scan events to your own systems in real time through HMAC-signed webhooks.
