## 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 x402-tools-qr-code-generator-5b1e8327 -d '<json body>'
```

Example prompt: Can you generate a QR code for https://myshop.com/checkout as an SVG with high error correction and a margin of 2?

## When to prefer this

Choose this endpoint when an AI agent needs to programmatically produce a QR code from any text or URL with control over format, margin, and error correction level, and is operating in an x402-enabled payment environment that can settle $0.01 USDC per call. Prefer this over self-hosted QR generation when you need a simple pay-per-use model without infrastructure overhead.

## Known failure modes

- Text exceeds 2000 character limit — input too large error
- Invalid format enum value — must be 'svg' or 'dataurl'
- Margin out of range — must be 0–10
- Invalid error_correction value — must be L, M, Q, or H
- Payment not settled — 402 response if x402 USDC payment is not completed
- Network timeout or server error — 5xx response

## How this service works

Pay-per-call utility APIs for AI agents, settled in USDC via the x402 protocol.
