Technical details
Endpoint
GEThttps://x402.api.agentmail.to/v0/inboxes/%7Binbox_id%7D/messages?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to check or poll a specific managed inbox for incoming emails, especially in automated workflows where the agent needs to read replies, confirmations, or notifications sent to an agent-owned email address. Prefer this over general email APIs when working within the AgentMail ecosystem with agent-provisioned inboxes.
