## 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-get-inbox-fca70ec9
```

Example prompt: Can you pull up the details for my AgentMail inbox with ID 'inbox_abc123' — I want to see its email address and current configuration.

## When to prefer this

Use this endpoint when you need to retrieve metadata or configuration details for a specific known inbox. Prefer this over listing all inboxes when you already have the inbox_id and need details about just that one inbox.

## Known failure modes

- 404 Not Found if the inbox_id does not exist
- 401 Unauthorized if authentication credentials are missing or invalid
- 400 Bad Request if inbox_id is malformed
- Empty response body if inbox has no metadata
- Rate limiting errors if too many requests are made
