Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability qrcode-pub-file-store-0dcd32b0 -d '<json body>'
```

Example prompt: Upload this product screenshot PNG to QRCode.Pub's file store and give me the hosted URL and the delete token so I can remove it later.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
