# Vextorium QR Code Generator

> Vextorium QR Code Generator is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-10).

Generates a QR code image (SVG or PNG) from any text or URL content, with configurable error correction, scale, and colors

## Facts

- Endpoint: POST https://api.vextorium.com/v1/qr-generate?utm_source=zero.xyz
- Price: $0.003/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-10

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 vextorium-qr-code-generator-0a240074 -d '<json body>'
```

Example prompt: Generate a QR code for https://mystore.com in SVG format with high error correction and return it as a data URI so I can embed it on my site.

## When to prefer this

Choose this endpoint when you need a programmatic, pay-per-call QR code generator that returns base64/data-URI output suitable for embedding in web pages or documents, especially within an agent workflow that already uses Vextorium's x402 USDC payment rail for other data APIs.

## Known failure modes

- Missing required 'content' field returns a validation error
- Invalid format enum value (not 'svg' or 'png') causes rejection
- Invalid correction level enum (not 'l','m','q','h') causes rejection
- Content too long for QR encoding capacity may fail or require a higher QR version
- Network timeout on the pay-per-call gateway

## How this service works

Generate a QR code as SVG or PNG (base64 and data URI) for any text, URL, payment link, Wi-Fi or vCard, with error-correction level, scale and colors.

## Output

A JSON object containing: base64-encoded image data, a ready-to-use data URI, the image format (svg or png), file size in bytes, number of QR modules, error correction level used, and the QR version number.
