## 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 barcode-generator-api-klymax402-com-b4264fc0
```

Example prompt: Generate a Code128 barcode for the text '7350053850019' with a height of 100 pixels and bar width of 2 pixels.

## When to prefer this

Use this endpoint when you need to programmatically generate a barcode image from a string or number, especially for inventory, retail, logistics, or labeling workflows. It supports multiple standard barcode formats (Code128, Code39, EAN-13, UPC-A) with configurable dimensions at a very low per-call cost.

## Known failure modes

- Invalid or unsupported barcode format specified — returns error indicating accepted formats
- Data string incompatible with chosen format (e.g. non-numeric data for EAN-13) — returns validation error
- Missing required 'data' parameter — returns bad request error
- Negative or zero dimensions provided — returns parameter validation error
- Payment not fulfilled via x402 protocol — returns 402 Payment Required
