## 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 mermail-get-thread-emails-acb4ed2f
```

Example prompt: Pull up all the emails in thread thread_abc123 from my Mermail mailbox mailbox_xyz456 so I can review the full conversation.

## When to prefer this

Use this endpoint when you need to read all messages within a specific, already-known email thread in a Mermail AI agent mailbox, as opposed to listing all threads or sending new messages. It is ideal for retrieving context before replying to a customer, reviewing a sales lead conversation, or verifying an order-related thread.

## Known failure modes

- Invalid mailboxId or threadId returns a 404 not found error
- Unauthorized access returns a 401 or 403 if credentials are missing or incorrect
- Empty thread returns emails array with zero items and totalCount of 0
- Malformed query parameters may result in a 400 bad request
- Network timeout or service unavailability returns a 503 or 5xx error

## How this service works

An inbox and wallet for your AI agent. Find and nurture sales leads, resolve customer support, and handle online purchases with controlled payments.

## Output

Returns a JSON object containing an array of email objects within the specified thread, each including id, subject, sender, recipient, date, body, read status, snippet, thread_id, scan_status, and content_omitted flag, along with a totalCount integer indicating the total number of emails in the thread.
