# WebberSites Barcode Generator API

> WebberSites Barcode Generator API is a paid API for AI agents from api.webbersites.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Generates print-ready barcodes in SVG and PNG formats for a wide range of 1D and 2D symbologies including Code 128, EAN-13, UPC-A, QR, ITF-14, and more

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 webbersites-barcode-generator-api-85203b10
```

Example prompt: Generate an EAN-13 barcode for the product number 5901234123457 — I need it as SVG and PNG, with the human-readable digits shown underneath.

## When to prefer this

Use this endpoint when you need server-side, deterministic barcode generation with no external dependencies — ideal for generating print-ready labels (product, shipping, inventory) in SVG+PNG without any client-side library. Supports the widest range of retail and logistics symbologies (EAN-13, UPC-A, ITF-14, GS1-128, Code 128, DataMatrix, PDF417, Aztec, Codabar). For QR codes specifically, use the sibling /api/qr endpoint.

## Known failure modes

- 400 error when data is invalid for the chosen symbology (e.g. wrong digit count for EAN-13 or UPC-A, bad check digit)
- 400 error when required 'data' query parameter is missing
- 400 error when an unsupported symbology type is specified
- Overly long data strings (>500 chars) may be rejected
- Malformed hex color values for dark/light params may produce unexpected results

## How this service works

Barcode generator for product, shipping, and inventory labels: GET ?data=&type= and receive a print-ready SVG plus PNG (base64) and a data: URI. Types: code128 (default), ean13, ean8, upca, upce, code39, itf14, gs1-128, codabar, datamatrix, pdf417, aztec. Check digits, quiet zones, and the human-readable line are handled per spec; invalid input for a symbology returns a clear 400. Deterministic, no network. QR codes live at /api/qr.

## Output

Returns a JSON object containing: an SVG string of the barcode, a base64-encoded PNG, and a data: URI — all print-ready with check digits, quiet zones, and a human-readable text line handled automatically per the chosen symbology's spec.
