# Batch Get Messages

`POST /v0/inboxes/{inbox_id}/messages/batch-get`

Fetch metadata for up to 500 messages in one request. Missing or
restricted IDs are silently omitted; compare `count` against `limit`
to detect misses.

**CLI:**
```bash
agentmail inboxes:messages batch-get --inbox-id <inbox_id> --message-id <id1> --message-id <id2>
```

## Path parameters

- `inbox_id` string, required — The ID of the inbox.

## Request body

- BatchGetMessagesRequest
  - `message_ids` MessageId[], required — IDs of messages to fetch. Maximum 500 ids per request. Duplicates are rejected with a validation error. IDs not found in the inbox (including cross-inbox or permission-restricted) are silently omitted from the response; callers detect misses by comparing `count` against `limit`.
