## 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 sindri-qr-code-generator-bc78c1ed -d '<json body>'
```

Example prompt: Can you generate a QR code for my website https://example.com and give me the image as a base64 PNG I can embed in my page?

## When to prefer this

Choose this endpoint when you need a fast, privacy-respecting QR code generated locally without sending data to a third-party QR service. Ideal for embedding in automated pipelines, generating QR codes for sensitive data (passwords, private URLs), or when you need a raw base64 PNG without external redirects or tracking.

## Known failure modes

- Text exceeds 500-character limit — request rejected with validation error
- Empty or missing text field — returns error indicating required parameter
- Text contains characters that cause QR encoding overflow — may return error
- Network or payment (x402) failure before the endpoint is reached

## How this service works

Generates a QR code for the given text, returned as a base64-encoded PNG data URL, computed entirely locally with no external service call.

## Output

A base64-encoded PNG data URL representing the QR code image, suitable for direct embedding in HTML img tags or saving as a .png file. The image encodes the submitted text or URL as a scannable QR code, computed locally with no external service dependency.
