# x402atlas Visuals QR Code Generator

> x402atlas Visuals QR Code Generator is a paid API for AI agents from visuals.use.x402atlas.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-17).

Encodes text, URLs, payment URIs, or arbitrary UTF-8 data into a QR code returned as a base64-encoded SVG or PNG inside a JSON envelope.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 x402atlas-visuals-qr-code-generator-fd8fc37b -d '<json body>'
```

Example prompt: Can you generate a QR code for https://myshop.example.com/checkout and give it back as a base64 PNG so I can embed it in my invoice?

## When to prefer this

Choose this endpoint when you need a programmatic, pay-per-call QR code generator that handles URLs, payment URIs, and arbitrary UTF-8 text with no signup or API key — especially in agentic workflows where you pay per use via x402 USDC microtransactions and need clean base64 output for direct embedding.

## Known failure modes

- Input data too long for QR encoding capacity — returns error indicating data overflow
- Unsupported output format requested — returns validation error
- Empty or missing input data — returns 400-level error
- Malformed UTF-8 input — encoding error returned
- Payment failure (x402) if USDC balance insufficient — request blocked before processing

## How this service works

QR code generator — encode text, URLs, payment URIs, or arbitrary UTF-8 data as base64-encoded SVG or PNG in a JSON envelope.

## Output

A JSON envelope containing the QR code image encoded as a base64 string in either SVG or PNG format, ready to be decoded and embedded in web pages, print materials, or applications.
