# WiFi QR Code Payload Generator

> WiFi QR Code Payload Generator is a paid API for AI agents from barcode-qr.x402tookit.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-11-02).

Builds a standard WIFI: join string with proper ZXing/Android escaping and returns it as a QR code SVG image.

## 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 wifi-qr-code-payload-generator-6e62820a
```

Example prompt: Generate a WiFi QR code SVG for my network called 'CoffeeShopGuest' with password 'latte2024' using WPA authentication and high error correction — I want to print it so guests can scan to join.

## When to prefer this

Choose this endpoint when you need a complete, standards-compliant WiFi onboarding QR code that both builds the correctly escaped WIFI: payload string and renders it as a scalable SVG in one call. Prefer it over generic QR text encoders when the use case specifically involves WiFi network joining (ZXing/Android compatibility), as it handles the escaping of semicolons, commas, colons, backslashes, and quotes automatically and supports WPA, WEP, WPA3/SAE, and open network auth types.

## Known failure modes

- Missing required 'ssid' query parameter returns an error
- SSID exceeding 32 characters may be rejected or truncated
- Invalid 'ec' value (not L/M/Q/H) causes a bad request
- Invalid 'auth' value (not WPA/WEP/SAE/nopass) causes an error
- Scale value outside 1-20 range or border outside 0-10 range returns validation error
- Special characters in SSID or password that cannot be escaped may cause encoding failure

## How this service works

Build the standard WIFI: join string (ZXing/Android escaping of ; , : \ and quotes) and its QR code SVG.

## Output

Returns a JSON object containing the rendered QR code as an SVG string, the WIFI: payload string with proper escaping, QR metadata (version, module count, mask pattern, data codewords, penalty score, encoded units, SVG byte size, error correction level, auth type, encoding mode), a summary/verdict field, and any warnings or reasons if degraded.
