## 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-domains-7ead2d65
```

Example prompt: Show me all the email domains registered under my AgentMail pod 'pod_abc123' — list up to 50, newest first.

## When to prefer this

Use this endpoint when you need to discover or audit which email domains are available under a specific AgentMail pod before creating inboxes, routing messages, or managing domain-level settings. Prefer this over Create Domain when you need to read existing state rather than provision new resources.

## Known failure modes

- Missing or invalid pod_id returns 404 not found
- Missing or invalid Authorization Bearer token returns 401 unauthorized
- Invalid page_token returns 400 bad request
- Pod with no domains returns empty domains array with count 0
- Rate limiting may return 429 too many requests

## How this service works

## Output

Returns a paginated list of domain objects for the specified pod, each containing domain_id (e.g. 'your-domain.com'), feedback_enabled flag, creation and update timestamps, and associated pod/client IDs. Also includes total count and next_page_token for pagination.
