## 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 payweave-storage-pay-per-call-file-upload-0549e652 -d '<json body>'
```

Example prompt: Upload this PDF to PayWeave Storage and keep it hosted for 30 days — I need a permanent URL I can share.

## When to prefer this

Choose this endpoint when you need a one-shot, pay-per-use file hosting solution with no subscription, a predictable $0.003 USDC cost per upload, and a permanent URL returned immediately. Ideal for ephemeral or short-lived file sharing needs where setting up persistent cloud storage accounts is overkill.

## Known failure modes

- Payment not received or insufficient USDC balance — upload rejected with 402
- Unsupported TTL value outside the allowed enum (1, 7, 30, 90, 365 days) — validation error
- File too large or missing — request rejected with 400
- Network timeout during upload — no URL returned

## How this service works

Pay-once file storage with permanent URLs.

## Output

A permanent URL pointing to the uploaded file, accessible for the selected TTL duration (1, 7, 30, 90, or 365 days).
