}Fetches metadata for one attachment on a message. 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. Attachment ids come from the attachments array on get_agentmail_inbox_message. The thread-level and draft-level twins are get_agentmail_inbox_thread_attachment and get_agentmail_inbox_draft_attachment.
Example
curl -X GET "https://api.aisa.one/apis/v1/agentmail/inboxes/{inbox_id}/messages/{message_id}/attachments/{attachment_id}" \
-H "Authorization: Bearer YOUR_API_KEY"
// Copy this whole block into Claude Code, Codex, Cursor or any coding agent.
// It carries everything needed to connect, authorize and run this example —
// no key to paste, one click of Allow in the browser.

// ── for the agent ─────────────────────────────────────────────────────────
// Register the AIsa MCP server, then call its `use` tool with the JSON above.
// name aisa

// transport streamable-http
// auth OAuth. The server publishes RFC 9728 metadata, so open a
// browser and the user clicks Allow once — nothing to paste.
// If AISA_API_KEY is set, send it as a bearer header instead.
// Use your own MCP mechanism, not a hand-edited config file:
// Codex codex mcp add aisa --url https://mcp.aisa.one/mcp
// Claude Code claude mcp add --transport http -s user aisa https://mcp.aisa.one/mcp
// Cursor / VS Code a "url" entry for https://mcp.aisa.one/mcp in the MCP config
// The server lists five tools over https://mcp.aisa.one/servers worth of APIs:
// search, get_details, use, batch_use, list_categories. search and
// get_details are free; use is billed per call and max_price_usd refuses
// anything above the cap before spending. This operation's full contract —
// every argument, the response shape, the price and the pitfalls — is at
// https://aisa.one/docs/api-reference/agentmail/get_agentmail-inboxes-inbox-id-messages-message-id-attachments-attachment-id.md
// Then run the call and show me the result.

opens a browser, you click Allow once, and there is no key to paste. The
commands per client, and what each call costs, are on
