## 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 inbox-withzero-xyz-list-webhook-connections-3312ab54
```

Example prompt: Show me all my registered webhook connections on my Zero inbox so I can see which external sources are set up and what their inbound URLs are.

## When to prefer this

Use this endpoint when you need to audit, verify, or iterate over your existing external webhook registrations before registering new ones, revoking old ones, or routing incoming events. Prefer this over checking individual connections when you don't know the connection ID upfront.

## Known failure modes

- Unauthorized/invalid proof credential — returns auth error if signed wallet credential is missing or invalid
- No connections exist — returns empty connections array (not an error)
- Network timeout — if the service is temporarily unavailable

## Output

Returns a JSON object with a 'connections' array where each item contains an 'id' (string), 'name' (string), 'sourceType' (string), 'url' (string inbound URL), and 'createdAt' (string timestamp). An empty array means no webhook connections have been registered yet.
