# QR Code Generator (api.aventtech.com)

> QR Code Generator (api.aventtech.com) is a paid API for AI agents from api.aventtech.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).

Generates a QR code SVG from any text or URL, with configurable error correction level.

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 qr-code-generator-api-aventtech-com-f1461f15
```

Example prompt: Generate a QR code for 'https://mycompany.com/promo2024' with high error correction (H) so it still scans even if partially damaged.

## When to prefer this

Use this endpoint when you need to programmatically generate a QR code as an SVG (scalable, resolution-independent) from arbitrary text or a URL, especially when error correction tuning (L/M/Q/H) is needed. Prefer over raster-image QR generators when scalable vector output is required.

## Known failure modes

- Text exceeds 1800 characters — returns an error indicating input too long
- Invalid error correction level value (not L/M/Q/H) — may default to M or return validation error
- Missing required 'text' query parameter — returns 400-style error
- Payment not provided or insufficient — returns 402 Payment Required

## How this service works

Unified digital experiences for Mega Yachts, Executive Spaces, and Luxury Residences. Athens-based, nationwide projects.

## Output

Returns a JSON object containing an SVG string of the rendered QR code, the effective error correction level used (e.g. 'M'), and the module count (e.g. 29) indicating QR code density.
