## 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-757e9e87 -d '<json body>'
```

Example prompt: Can you generate a QR code for https://mystore.example.com so I can print it on my flyers?

## When to prefer this

Prefer this endpoint when you need a quick, private, locally-computed QR code without sending data to a third-party QR generation service. Ideal for agents that need to embed QR codes in documents or UIs programmatically, or when privacy of the encoded content matters. The base64 PNG output is directly embeddable in HTML or saveable as a file with no extra processing.

## Known failure modes

- Text exceeds 500 characters — request will be rejected or QR code will fail to encode
- Empty or missing 'text' field — likely returns an error response
- Malformed request body — returns a 400-level error
- Lambda cold start may add latency on rare occasions

## 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 generated QR code image, which can be embedded directly in HTML (as an <img> src), saved to disk, or displayed in a UI without any additional decoding step.
