How this service works
Generate and decode QR codes with x402 payments and an MCP server.
Output
Returns a JSON object with a count of generated QR codes and a results array. Each result includes the original data string, its index in the batch, the optional label, PNG image dimensions (width/height in pixels), border size, QR version, number of modules, box size, background and fill colors, file size in bytes, the full base64-encoded PNG image, and the error correction level used.
Example use cases
Event ticket QR code batch
“I need QR codes for 10 event check-in URLs — each one is like https://events.mycompany.com/ticket/1 through /ticket/10. Generate them all at once with labels like 'Ticket 1', 'Ticket 2', etc. so I can print them.”
Restaurant menu item links
“Can you make QR codes for five of our menu items? The URLs are https://menu.tastybistro.com/burger, /pizza, /salad, /pasta, and /dessert — label each one with the dish name so we can put them on table cards.”
Marketing campaign landing pages
“Generate QR codes for our three campaign landing pages: https://brand.com/summer-sale labeled 'Summer Sale', https://brand.com/newsletter labeled 'Newsletter Signup', and https://brand.com/app-download labeled 'Download App'. We need the images to print on flyers.”
Technical details
Endpoint
POSThttps://qr.payapi.market/generate/batch?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to generate multiple QR codes in a single API call (up to 20 at a time), reducing latency and cost compared to making individual requests. Ideal for bulk workflows like printing campaigns, event ticketing, product catalogs, or any scenario requiring a batch of QR images delivered as base64 PNGs with structured metadata.
Side effects
- Exceeding the 20-item batch limit returns a validation error
- Missing required 'data' field on any item causes rejection
- Payment failure (insufficient USDC balance) blocks the request
- Invalid or empty data strings may produce malformed QR codes
- Very long data strings may increase QR version and image size unexpectedly
