Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-get-email-attachment-fec5ba46
```

Example prompt: Fetch the attachment with ID attach_abc123 from thread thread_xyz789 in my AgentMail pod pod_001 so I can read the file that was sent.

## When to prefer this

Use this endpoint when an AI agent needs to retrieve a specific email attachment it already knows the ID of — for example, after listing threads or messages and identifying a relevant attachment. Prefer this over generic file storage retrieval when working within the AgentMail ecosystem for agent-driven email workflows.

## Known failure modes

- 404 if pod_id, thread_id, or attachment_id does not exist or is not accessible
- 401/403 if authentication is missing or insufficient
- 400 if required path parameters are malformed or missing
- Empty or minimal response if attachment has no metadata

## 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 JSON containing the attachment data and/or metadata for the specified attachment in the given email thread and pod — including content, filename, MIME type, or download URL depending on the API response structure.
