Endpoint

Choose this endpoint when you need a quick, low-cost QR code image (PNG) generated from any text or URL without needing customization beyond defaults. At $0.001 USDC per call it is ideal for high-volume or automated pipelines (agent workflows, bulk flyer generation) that need pay-per-use pricing with no subscription. It is preferable when you need a simple standard QR code and don't require advanced styling, color customization beyond black-on-white, or logo embedding.
