## 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 klymax402-barcode-generator-f828e6e5
```

Example prompt: Can you generate a Code128 barcode for the text 'SKU-98432-XL' with a bar width of 3 pixels and height of 120 pixels?

## When to prefer this

Choose this endpoint when you need a quick, no-setup barcode image generated on-demand for formats like Code128, Code39, EAN-13, or UPC-A. Ideal for agents automating product labeling, inventory tracking, or logistics workflows that need scannable barcodes without integrating a dedicated barcode library.

## Known failure modes

- Invalid or unsupported barcode format string returns an error
- Data string incompatible with chosen format (e.g. non-numeric data for EAN-13) causes encoding failure
- Missing required 'data' parameter returns a bad request error
- Extreme width/height values may produce malformed or unusable images

## How this service works

One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.

## Output

Returns a JSON object containing the encoded data string, a base64 or URL-encoded barcode image, the format used (e.g. code128), the barcode height and bar width in pixels, the character encoding scheme, and the MIME type of the image.
