## 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 forgemesh-qr-code-generator-55ad7ec2 -d '<json body>'
```

Example prompt: Can you generate a QR code for the URL https://pay.example.com/invoice/1234, at 512 pixels wide, so I can put it on a printed invoice?

## When to prefer this

Use this endpoint when you need a quick, on-demand QR code generated from a URL or text string and returned as a base64 PNG without any server-side storage. Ideal for automated workflows that embed QR codes in invoices, digital documents, or printed materials without requiring a design tool or manual steps.

## Known failure modes

- Input text exceeds 2000 characters — request rejected
- Size parameter outside 128–1024 range — may return error or use default
- Malformed JSON body — 400 Bad Request
- Payment not provided or insufficient — 402 Payment Required
- Service unavailable — 5xx response

## How this service works

On-demand QR code creation from plain text or a URL, configurable size from 128 to 1024 pixels with medium error correction baked in, returned as a base64 PNG with nothing retained afterward. Useful for payment links, business cards, table tents, and any workflow that needs a fresh scannable code generated in milliseconds rather than through a design tool.

## Output

A base64-encoded PNG image of a QR code encoding the submitted text or URL, sized between 128 and 1024 pixels with medium error correction. No data is retained server-side after the response.
