## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tanod-utilpeek-barcode-generator-96ea348d -d '<json body>'
```

Example prompt: Generate an EAN-13 barcode image in SVG format for the product number 590123412345, with the human-readable number shown beneath the bars.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call barcode image generator supporting the most common retail and logistics symbologies (Code 128, Code 39, EAN-13, EAN-8, UPC-A, ISBN-13) with flexible SVG or PNG output. Prefer it over full-stack label-printing services when you only need a single barcode image embedded in a document, printed label, or UI.

## Known failure modes

- Data string violates symbology constraints (e.g. Code 39 contains non-permitted characters) — likely 400 error
- EAN/UPC/ISBN digit count or check digit is incorrect — likely 400 error
- Data string exceeds maxLength of 80 characters — rejected
- Empty data string (minLength 1 not met) — rejected
- Unsupported format or type enum value — likely 400 or validation error

## How this service works

## Output

Returns a barcode image: an SVG string (for svg format) or a base64-encoded PNG (for png format) representing the encoded data in the requested symbology, optionally with a human-readable line beneath the bars.
