## 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 webbersites-scratchpad-storage-api-eacefe9a
```

Example prompt: Show me all my scratchpad pads — I want to see each pad's name, how many bytes it's using, and when it expires.

## When to prefer this

Use this endpoint when an AI agent needs to inspect or audit its own stored scratchpad memory entries, check storage usage, or identify pads nearing expiration — especially within the WebberSites x402 ecosystem where scratchpad state is used for keyless agent persistence.

## Known failure modes

- Invalid or missing wallet auth returns 402 or 401 error
- No pads exist yet returns empty pads array
- Malformed properties filter parameter may return 400
- Expired payment token causes 402 re-challenge

## How this service works

List your wallet's scratchpads: names, sizes, updated and expiry dates. The cheap 'do I have memory here?' call for the start of a session.

## Output

A JSON object containing a list of named scratchpad pads, each with a name, byte size, expiry datetime, and last updated datetime, plus the associated wallet address.
