}Fetches metadata for one attachment in a thread addressed by id alone. Returns
Set this endpoint up in your agent →
attachment_id, filename, size, content_type, content_disposition, content_id and a short-lived download_url with expires_at. The bytes are not inlined — fetch download_url before it expires. This is the organization-wide view spanning every inbox in the account. Every AIsa caller shares one AgentMail account, so this reaches inboxes other callers created; the inbox-scoped twin get_agentmail_inbox_thread_attachment is the one to use when a single inbox is meant.

-H "Authorization: Bearer YOUR_API_KEY"
// Copy this whole block into Claude Code, Codex, Cursor or any coding agent.
