If you're using QR API and have exceeded the monthly API request limit, an API request will return the following error:
{"error":User API request limit has expired}
To increase monthly limit, you will need to upgrade to a higher plan. See our Plans & Pricing. To upgrade to a higher plan, login to your API account and upgrade your subscription.
If you still have any questions, feel free to reach out to the support team at qrapi.support@scanova.io.
