## 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-drafts-c525e332
```

Example prompt: Show me all the drafts saved in AgentMail inbox 'inbox_abc123' — up to 20 of them, filtered to those labeled 'follow-up', sorted from newest to oldest.

## When to prefer this

Use this endpoint when an AI agent needs to inspect, review, or manage unsent email drafts within a specific AgentMail inbox — especially useful for automation workflows that check pending outbound messages, retrieve scheduled drafts, or audit draft content before sending. Prefer this over a general email list endpoint when specifically targeting draft state rather than sent or received messages.

## Known failure modes

- Invalid or missing inbox_id returns 404 not found
- Expired or invalid Bearer token returns 401 unauthorized
- Invalid date-time format for before/after filters returns 400 bad request
- Non-existent label filter returns empty drafts array with count 0
- Invalid page_token returns 400 or empty results
- Rate limiting may return 429 too many requests
