QRLoot API is a RESTful API that allows developers to generate and serve QR codes as well as monetize their API usage. With QRLoot, developers can easily generate a QR code image by sending a URL through an API endpoint, and retrieve the image file through another endpoint. The API also provides tools for tracking and monitoring API usage, as well as managing billing and payments. By integrating QRLoot into their applications, developers can provide their users with a convenient way to scan and access information, while generating revenue through a flexible and transparent monetization model.
