## 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 voixoff-fr-qr-code-generator-x402-mcp-1186b351 -d '<json body>'
```

Example prompt: Generate a QR code for the URL https://myshop.com — give me the result as a base64 PNG I can embed in a flyer.

## When to prefer this

Choose this endpoint when you need a quick, serverless QR code generation with MCP tool interface support and x402 micropayment billing at $0.01 per call. It supports four QR types (URL, text, vCard, WiFi) and returns a base64 PNG ready for embedding. Prefer it for agent workflows that need programmatic QR code creation without managing image storage.

## Known failure modes

- Invalid or missing 'type' field (must be one of: URL, text, vCard, WiFi) causes a validation error
- Malformed vCard or WiFi credential structure may produce an unreadable QR code
- Missing required 'toolName' or 'inputSchema' in the MCP wrapper leads to a 400-level error
- Payment failure (insufficient USDC balance) blocks the request before generation
- Extremely long text inputs may exceed QR code capacity limits
