Overview

This AWS Lambda function is a Python-based microservice for generating Rectangular Micro QR (rMQR) codes with the API. Specify data, size preference, and error correction level to get a customized rMQR code. Ideal for space-constrained or unique design applications, get a fast, reliable, and easy-to-integrate solution for your rMQR code generation needs.

rMQR Code Generation API

Generate Rectangular Micro QR (rMQR) codes on-the-go with our simple yet powerful API. Tailored for space-constrained or unique design applications, it's now easier than ever to integrate rMQR code generation in your projects.

Endpoint

POST /generate-rmqr

Request Parameters

• data (string, required): The data to be encoded in the rMQR code. Max 200 characters.
• size (string, optional, default: "balanced"): The size preference for the rMQR code. Acceptable values are:
  • minimize_height
  • minimize_width
  • balanced
• error_correction_level (string, optional, default: "auto"): The error correction level for the rMQR code. Acceptable values are:
  • M
  • H
  • auto (defaults to M)

Example Request

{
  "data": "https://example.com",
  "size": "balanced",
  "error_correction_level": "M"
}

Response

The API responds with a JSON object containing the base64-encoded PNG image of the generated rMQR code.

• rmqr_image_base64 (string): The base64-encoded PNG image of the generated rMQR code.

Example Response

{
  "rmqr_image_base64": "iVBORw…"
}

Error Handling

In case of an error, the API will return a 500 Internal Server Error status code along with a JSON object containing an error key with a string value describing the error.

Example Error Response

{
  "error": "Data cannot be empty."
}
