## 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 qr-code-generator-x402-forgemesh-io-75686c0c -d '<json body>'
```

Example prompt: Can you generate a QR code for https://pay.example.com/invoice/12345 at 512px so I can drop it into a PDF invoice?

## When to prefer this

Choose this endpoint when you need a fast, privacy-preserving QR code generated server-side without storing the input — ideal for payment links, tickets, or onboarding flows where latency must be minimal and data sensitivity is a concern. Prefer it over client-side libraries when you need a consistent base64 PNG output suitable for embedding in documents, emails, or print pipelines.

## Known failure modes

- Input text exceeds 2000 characters — request rejected
- Invalid or out-of-range size parameter (below 128 or above 1024px) — may return error or default
- Malformed request body — 400-level error
- Payment failure or insufficient USDC balance — 402 Payment Required
- Service temporarily unavailable — 5xx error

## How this service works

QR code generator API: turn any text or URL (up to 2000 characters) into a scannable PNG QR code, returned as base64 — size configurable 128-1024px, medium error correction. Generated locally in milliseconds; input never stored. Use for payment links, event tickets, Wi-Fi sharing, onboarding flows, and print materials.

## Output

A base64-encoded PNG image of the QR code, ready to embed in HTML (as a data URI), decode to a file, or pass to a print pipeline. The image encodes the submitted text or URL with medium error correction at the requested pixel size.
