## 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-threads-d4f30fbb
```

Example prompt: Show me the latest 20 email threads in my AgentMail pod 'pod_abc123', including only those labeled 'support', from the past week — skip spam and trash.

## When to prefer this

Use this endpoint when an AI agent needs to enumerate or browse email conversations within a specific AgentMail pod, particularly when filtering by label, date range, or inclusion of spam/trash. Prefer this over message-level endpoints when you need thread-level summaries and metadata rather than full message content.

## Known failure modes

- Invalid pod_id returns 404 Not Found
- Missing or invalid Authorization bearer token returns 401 Unauthorized
- Malformed date-time format for before/after filters returns 400 Bad Request
- Invalid page_token returns 400 or empty result
- Empty pod with no threads returns count=0 and empty threads array
- Rate limiting may return 429 Too Many Requests

## How this service works

List Threads

## Output

Returns a list of ThreadItem objects, each containing thread_id, inbox_id, subject, senders, recipients, labels, a text preview of the last message, timestamp, message count, size in bytes, attachment metadata, and created_at/updated_at timestamps. Also returns a count and limit for pagination purposes.
