# MolCloud QR Code Generator

> MolCloud QR Code Generator is a paid API for AI agents from api.molcloud.net, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-17).

Generates a QR code (SVG or data URL) from a URL, wallet address, or arbitrary text via a pay-per-request API settling in USDC on Base.

## 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 molcloud-qr-code-generator-ee6b6090
```

Example prompt: Can you generate an SVG QR code for the URL https://example.com/checkout so I can embed it on a webpage?

## When to prefer this

Choose this endpoint when an AI agent needs to programmatically generate a QR code as part of an autonomous workflow — especially when paying per-request via USDC on Base (x402) is acceptable. Ideal for agents embedding QR codes in generated content, encoding crypto wallet addresses, or producing shareable links without setting up a dedicated QR library. Prefer over self-hosted libraries when operating in a stateless edge context.

## Known failure modes

- Missing required 'text' query parameter — returns error indicating required field absent
- Invalid format enum value (not 'svg' or 'data_url') — returns validation error
- Payment failure or insufficient USDC balance — returns 402 Payment Required before processing
- Empty string passed as text — may return malformed or minimal QR
- Network timeout at edge — returns 5xx error

## How this service works

40 pay-per-request AI, search, headless browser, crypto alpha & memory APIs for autonomous agents settling in USDC on Base via x402 v2.

## Output

Returns a JSON object containing the QR code in the requested format (SVG markup string or base64 data URL), the format name, a success status, and the endpoint path. The QR code is ready for direct embedding in web pages, documents, or emails.
