How this service works
AgentMail gives AI agents real email inboxes. Create, send, receive, and search messages via REST API — built for autonomous agents and agentic workflows.
Output
Returns a JSON list of email messages matching the specified direction (e.g. inbound or outbound) and type, including message metadata such as sender, recipient, subject, and timestamps.
Example use cases
Example prompt
“Show me all inbound emails of type 'message' from my AgentMail inbox — I want to see what messages my agent has received so far.”

Endpoint
GEThttps://x402.api.agentmail.to/v0/lists/%7Bdirection%7D/%7Btype%7DWhen to prefer
Use this endpoint when you need to list and browse email messages filtered by direction (inbound vs outbound) and message type within an AgentMail agent inbox. Prefer this over generic email APIs when building autonomous AI agent workflows that require programmatic access to structured email lists with x402 micropayment support.
