# QR Code Generator

> QR Code Generator is a paid API for AI agents from skinwinking.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-31).

Generates a QR code (SVG and base64 GIF) from a text string with configurable error correction and cell size

## Facts

- Price: $0.001/call
- Payment: x402

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-1a2e503a
```

Example prompt: Generate a QR code for the text 'https://myshop.com/checkout' using high error correction (H) and a cell size of 8.

## When to prefer this

Choose this endpoint when you need a quick, server-side QR code generation with dual output formats (SVG + GIF) in a single call, especially within an x402 micropayment workflow. It is ideal when you want a pay-per-use model at $0.001 per call without maintaining API keys or a subscription. Prefer it when you need both a scalable vector format (SVG) and a raster format (GIF) simultaneously.

## Known failure modes

- Text exceeds 2000 characters — request rejected
- Invalid error correction level (not L, M, Q, or H) — bad request error
- Cell size outside 1–20 range — validation error
- Missing required 'text' query parameter — error response
- Payment not fulfilled via x402 — 402 Payment Required response

## How this service works

50 pay-per-call tools for agents over x402 (USDC on Base, Polygon, Solana): crypto market data, token audits, indicators, swap routing, web extraction, DNS/WHOIS/email checks, FX, weather and AI text/image tools.

## Output

Returns a JSON object containing two representations of the QR code: an 'svg' field with an inline SVG string ready for web embedding, and an 'image' field with a base64-encoded GIF data URI suitable for use in HTML img tags or download.
