How this service works
Create editable (dynamic) QR codes that never expire. One-time payment from $9, unlimited scans, change the link any time, scan counts included. Free static QR code generator too.
Output
Returns a JSON object containing a unique file ID, a public hosted URL (e.g. https://qrcode.pub/f/{id}), the original file name, MIME type, file size in bytes, a secret bearer token for deletion, a DELETE endpoint instruction, and an expiry timestamp.
Example use cases
Share product image via link
“Upload this product photo JPEG to QRCode.Pub's file store and send me back the public URL and the secret token I'll need to delete it later.”
Host PDF for QR code target
“I want to create a dynamic QR code that points to a PDF brochure — first upload this PDF to QRCode.Pub's store so I get a hosted URL to point the QR code at, and give me the file ID and deletion token.”
Temporarily host a JSON data file
“Can you upload this JSON file to QRCode.Pub's temporary file store and give me the hosted link and the token to delete it when I'm done?”
Technical details
Endpoint
POSThttps://qrcode.pub/x402/store?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to temporarily host a file and get a public URL — particularly useful as a precursor step to creating a QR code that points to the file. It's well-suited for small to medium files in common formats (images, PDFs, JSON, CSV, text/markdown) that need a short-lived public link with a known expiry and a deletion mechanism. Prefer this over generic file storage when you're already working within the QRCode.Pub ecosystem or want a pay-per-use model with no subscription.
Side effects
- Unsupported file type returns an error — only image/png, image/jpeg, image/webp, image/gif, application/pdf, application/json, text/plain, text/markdown, text/csv are accepted
- Payment failure or insufficient USDC balance prevents upload
- File too large may exceed undocumented size limits
- Lost deletion token means file cannot be removed before expiry
- File expires around 2026-11-04 — links will break after that date
