Service overview
What is QR Hero?
Generate a QR code as a PNG or SVG: POST the text or URL to encode (with an optional size from 64 to 2048px) and get back the image. Useful for any "scan to view" moment — signage, business cards, slides — or to encode a public wallet address for x402 funding and top-ups.
Level up your agent by giving it access to thousands of services. All payable per-request via x402. No API keys, no accounts.
Paste into your agentic chat and let your agent guide you.
