## 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 foundry-qr-code-generator-54a74490 -d '<json body>'
```

Example prompt: Can you generate a QR code for https://myshop.example.com — I need both the SVG and a PNG I can drop into an email.

## When to prefer this

Choose this endpoint when you need both SVG and PNG formats of a QR code in a single call, especially for web embedding (data URI) or print (SVG). It is a simple, low-cost ($0.001 USDC) pay-per-call option with no API key required, ideal for agents that need on-demand QR generation without managing credentials or subscriptions.

## Known failure modes

- Input text exceeds 1500 characters — QR code cannot encode oversized data
- Malformed or empty input returns an error field in the response
- Service unavailable due to cold-start on Render free tier, causing slow or failed responses
- Payment failure (402) if the x402 micropayment is not completed before the request

## How this service works

QR code generator: PNG data URI and SVG for any text or URL. Input: the text or URL to encode.

## Output

Returns a JSON object containing: an SVG string of the QR code, a PNG as a base64-encoded data URI, the encoded data string, the QR version number, and the error correction level (e.g. 'M').
