## 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-mailbox-email-list-482858ad
```

Example prompt: Check my Mermail inbox for the latest 20 emails in the support folder, sorted by date descending, and only show me ones that have been scanned as clean — just metadata, no body content.

## When to prefer this

Use this endpoint when your AI agent needs to programmatically read, filter, and process incoming emails from a Mermail managed inbox — especially when you need safety scanning (clean/flagged/skipped), agent-safe content formatting, or metadata-only retrieval to protect downstream systems. Prefer this over general email APIs when you need built-in payment-gated access and agent-first design.

## Known failure modes

- Invalid or unknown mailboxId returns 404 or empty result
- Invalid cursor value causes pagination error
- Exceeding limit of 100 per page returns validation error
- Requesting non-existent folder returns empty email list
- Payment not processed (x402) results in 402 Payment Required before data is returned
- Invalid enum value for sortColumn or sortDirection returns 400 error
- Scan status filter with no matching emails returns empty list with totalCount 0

## 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 paginated list of emails with fields including id, subject, sender, recipient, date, body (if not metadata_only), snippet, thread_id, read status, scan_status, and content_omitted flag, along with a totalCount of matching emails.
