How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
A JSON object containing: a base64-encoded data URI of the QR code image (PNG or SVG), the QR version and module count, SHA-256 hashes of both the output image and the input data, the format and media type, the model used (qrcode-python), the sale price in USDC, and an attribution note. The data URI can be embedded directly in HTML or saved as an image file.
Example use cases
QR code for product landing page
“Make a QR code for https://acmecorp.com/product/launch in PNG format with H error correction so it still scans if the printout is a bit smudged — I want to put it on a flyer.”
Wi-Fi password QR code for a cafe
“Generate a QR code encoding the text WIFI:S:CoffeehouseGuest;T:WPA;P:Latte2024;; as a PNG with border 4 and medium error correction, so my customers can scan and connect instantly.”
SVG QR code for a business card
“Can you create an SVG QR code for my LinkedIn profile URL https://linkedin.com/in/janedoe with a box size of 6 and low error correction? I need the vector format so it scales cleanly on a printed card.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/qr-code?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a verifiable, pay-per-use QR code generation with no account signup, cryptographic proof of delivery (SHA-256), and USDC micropayment settlement on Base or Solana via x402. Ideal for AI agents that need to generate QR codes on-demand without managing API keys or subscriptions. Prefer this over free tier services when auditability and on-chain payment receipts matter.
