## 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 vextorium-barcode-generator-svg-987c0d5d -d '<json body>'
```

Example prompt: Generate an EAN-13 barcode SVG for the code 841007647234 — please include the visible text below the bars so I can use it on a product label.

## When to prefer this

Choose this endpoint when you need server-side, scalable barcode SVG generation without installing local libraries, especially when check-digit computation is needed or when integrating barcode creation into an automated label-printing or product-management workflow. Ideal for agents that need a vector (SVG) output suitable for both screen display and high-resolution printing.

## Known failure modes

- Invalid or malformed barcode code for the selected symbology returns an error
- Barcode type string does not match a supported symbology name
- Code length mismatch for fixed-length formats like EAN-13 or EAN-8
- Missing required 'codigo' field results in validation error
- Unsupported combination of type and code content

## How this service works

Generate a barcode as SVG (EAN-13, EAN-8, UPC-A, ISBN, ISSN, Code 128, Code 39, ITF, GS1-128...) for labels and products, computing the check digit when missing.

## Output

Returns a JSON object containing the barcode type used, the complete barcode code (including computed check digit), the SVG image as a base64 string, a ready-to-embed data URI (data:image/svg+xml;base64,...), and the file size in bytes.
