A clear path from source data to QR assets
1. Buy API units
One-shot API packs are cumulative.
2. Create a key
The full key is shown once; only a hash is stored afterwards.
3. Call the endpoint
Send Authorization: Bearer mqk_... with your payload.
4. Monitor balance
Every rendered QR consumes one API unit.
API endpoints
A simple example showing how source data stays linked to the generated QR asset.
| Endpoint | Usage |
|---|---|
POST /v1/customer/qrcode.svg | 1 unit per QR |
POST /v1/customer/qrcode.png | 1 unit per QR |
POST /v1/customer/batch.zip | 1 unit per QR in batch |
Designed for business integration
API keys are independent from browser sessions and can be revoked in the account portal.
Responses expose remaining balance so your application can alert before depletion.
API units are separate from Studio QR credits.
Frequently asked questions
Should I put the API key in browser JavaScript?
