## 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 agentsvc-io-qr-code-generator-55a69490 -d '<json body>'
```

Example prompt: Can you generate a QR code for https://mystore.com/sale — make it 512 pixels wide and use high error correction (H level) so it's more durable?

## When to prefer this

Choose this endpoint when an AI agent needs to generate a QR code on demand without maintaining an API key or account. Ideal for single-call, pay-per-use workflows using USDC on Base via x402. It returns a base64 image directly, making it easy to embed in documents, emails, or web pages without an intermediate file storage step.

## Known failure modes

- Text input missing — returns validation error
- Size outside allowed 64–1024 pixel range — returns error
- Invalid error_correction value — returns validation error
- Text too long for selected size and error correction level — may return error or degraded QR
- Network timeout — no response returned

No account, no API key, free sample on every service.

## Output

Returns a JSON object containing the original text, image width and height in pixels, a UTC generation timestamp, and a base64-encoded PNG string of the QR code image ready for embedding in HTML or decoding to a file.
