How this service works
QR code generation API for agents at $0.001 USDC. Call when you need a PNG or SVG QR from text or a URL for tickets, onboarding links, or receipts—without installing a QR library. Returns a self-contained data URI plus SHA-256 receipt via x402 on Base; the encoded destination is never fetched or validated. No API key, no subscription.
Output
A self-contained data URI (base64-encoded PNG or raw SVG) representing the QR code, along with a SHA-256 receipt confirming the generation. No external fetch is performed on the encoded content. The image can be embedded directly in HTML, documents, or printed materials.
Example use cases
QR code for event check-in link
“Make a QR code for https://events.mycompany.com/checkin/2024 as an SVG with error correction set to H and a border of 4 — we're printing it on signage so it needs to be durable.”
Embed Wi-Fi credentials as QR code
“Create a PNG QR code that encodes the string WIFI:T:WPA;S:GuestNetwork;P:Welcome2024;; so guests can scan it to join our Wi-Fi — use medium error correction and keep the box size at 4.”
Shareable product page QR code
“Turn this URL into a QR code for our product flyer: https://store.example.com/products/widget-pro — PNG format, error correction M, border 3.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/qr-code?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, first-party QR code with a cryptographic SHA-256 receipt and no third-party tracking or URL fetching. Ideal for privacy-sensitive use cases, automated pipelines requiring proof of generation, or when you need a self-contained data URI (no hosted image URL). Prefer SVG format for print/scalable use and PNG for web embedding.
Side effects
- Empty or missing 'data'/'text' field returns a validation error
- Input exceeding 2048 characters is rejected
- Invalid enum values for format or error_correction return a 422 error
- box_size or border outside allowed range returns a validation error
- Payment failure or insufficient USDC balance results in a 402 response
