## Documentation

## Deploy and Host a Barcode Generation API with Railway

A production-ready REST API for generating barcodes and QR codes. Supports Code128, EAN-13, Code39, UPC-A, ISBN-13, QR codes, and more. Returns SVG or PNG. No database needed — pure computation.

## About Hosting Barcode Generation API

The app uses Python + python-barcode library to generate barcodes and the qrcode library for QR codes. Each request is stateless and lightweight — no external APIs, no database, no background workers. Results are returned as SVG (scalable, tiny file size) or PNG (rasterized). Ideal for e-commerce, inventory management, logistics, and ticketing systems.

## Common Use Cases

- **E-commerce** — Generate barcodes for product labels and SKU tags
- **Inventory management** — Print barcode labels for warehouse items
- **Ticketing** — Generate QR codes for event tickets and passes
- **Logistics** — Create shipping labels with barcodes
- **Retail** — Generate price tags and shelf labels
