## 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 agentmail-inbox-id-4b0aaca4
```

Example prompt: Can you pull up the details for the AgentMail inbox with ID 'inbox_abc123' — I need to see its display name and when it was created.

## When to prefer this

Use this endpoint when you need to verify the existence of a specific inbox, retrieve its display name, pod association, or creation/update timestamps. Prefer this over listing all inboxes when you already have the inbox_id and need a direct, efficient lookup.

## Known failure modes

- inbox_id not found — returns 404 Not Found
- missing or invalid Authorization Bearer token — returns 401 Unauthorized
- malformed inbox_id format — may return 400 Bad Request
- inbox belongs to a different account — returns 403 Forbidden
