How this service works
50 pay-per-call tools for agents over x402 (USDC on Base, Polygon, Solana): crypto market data, token audits, indicators, swap routing, web extraction, DNS/WHOIS/email checks, FX, weather and AI text/image tools.
Output
Returns a JSON object containing two representations of the QR code: an 'svg' field with an inline SVG string ready for web embedding, and an 'image' field with a base64-encoded GIF data URI suitable for use in HTML img tags or download.
Example use cases
QR code for event check-in
“Make a QR code for the URL 'https://events.mycompany.com/checkin/2024' with medium error correction and a cell size of 6 — I need it as an SVG to embed in our event flyer.”
Encode Wi-Fi credentials as QR
“Create a QR code that encodes 'WIFI:S:GuestNetwork;T:WPA;P:welcome123;;' so guests can scan it to connect — use high error correction (H) and cell size 10.”
QR code for crypto wallet address
“Generate a QR code from the Bitcoin address 'bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh' with error correction level Q and cell size 7, so I can print it on a tip card.”
Technical details
Endpoint
GEThttps://skinwinking.com/api/v1/util/qr-code?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, server-side QR code generation with dual output formats (SVG + GIF) in a single call, especially within an x402 micropayment workflow. It is ideal when you want a pay-per-use model at $0.001 per call without maintaining API keys or a subscription. Prefer it when you need both a scalable vector format (SVG) and a raster format (GIF) simultaneously.
Side effects
- Text exceeds 2000 characters — request rejected
- Invalid error correction level (not L, M, Q, or H) — bad request error
- Cell size outside 1–20 range — validation error
- Missing required 'text' query parameter — error response
- Payment not fulfilled via x402 — 402 Payment Required response
