## 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 nexusapi-qr-code-generator-55cfa5f8 -d '<json body>'
```

Example prompt: Can you generate a QR code for https://myshop.com/menu so I can put it on my restaurant's table cards?

## When to prefer this

Use this endpoint when you need to programmatically generate a QR code from a URL or text string without managing API keys. Ideal for agent workflows where on-demand QR code creation is needed per-call with pay-per-use USDC billing.

## Known failure modes

- Empty or missing query string returns an error
- Input data too long to encode in a standard QR code
- Malformed input may produce an unreadable QR code
- Payment failure (402) if USDC balance is insufficient
- Upstream service timeout returns a 5xx error

## How this service works

Crypto, AI, Social Media, Finance, Weather, Tools &amp; more. Pay per call in USDC on Base. No API keys.

## Output

The agent receives a QR code image (or image URL/data) encoding the provided input text or URL, ready for display, download, or embedding.
