## 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-zone-file-retrieval-8b05574e
```

Example prompt: Can you fetch the DNS zone file for domain ID 'acme-corp' inside AgentMail pod 'pod-abc123'? I want to see the current DNS records configured for that email domain.

## When to prefer this

Use this endpoint when you need to inspect, audit, or verify the DNS zone configuration for a specific email domain managed within an AgentMail pod. Ideal when setting up email routing, debugging deliverability issues, or confirming DNS records are correctly provisioned for an AI agent's inbox domain.

## Known failure modes

- pod_id or domain_id not found — likely 404 error
- Unauthorized access if authentication token is missing or invalid
- Domain does not belong to the specified pod — mismatch error
- Empty or malformed zone file if domain is newly provisioned
- Rate limiting or payment required (x402) if free tier exceeded

## How this service works

AgentMail gives AI agents real email inboxes. Create, send, receive, and search messages via REST API — built for autonomous agents and agentic workflows.

## Output

Returns a JSON object containing the DNS zone file data for the specified domain within the given AgentMail pod, including DNS records and configuration entries used to route email for that domain.
