## About

## What it does
Barcode Generator turns a text value into a barcode PNG. Send `data` and choose a `format` of `code128`, `ean13`, `ean8`, `isbn13`, or `upca`; the response is the rendered image as binary output.

Use it when you need barcodes for product labels, shipping workflows, inventory systems, or printable asset tags. Because the endpoint returns a PNG, you can store it, stream it to a browser, or place it directly into a document or label template.

Barcode Generator is a good fit when your application already knows the code value and just needs a clean, machine-readable image. It supports a default `code128` format for general-purpose encoding, plus common retail and publishing formats for UPC and ISBN use cases.

Keep the payload simple: pass the barcode content in `data`, select the symbology that matches your workflow, and use the returned PNG wherever the barcode needs to appear.
