Endpoint
GEThttps://x402.api.agentmail.to/v0/inboxes/%7Binbox_id%7D/messages/%7Bmessage_id%7DWhen to prefer
Use this endpoint when you need to retrieve the full details of a specific, known email message from an AgentMail inbox and already have both the inbox_id and message_id. Prefer this over listing endpoints when you only need one specific message rather than browsing multiple messages.
