AgentInbox is an API-first email platform designed for AI agents and automated workflows. It provides temporary email inboxes, real-time email processing, and structured data extraction.

Inboxes have a configurable time-to-live (TTL) from 1 second up to 7 days. After the TTL expires, the inbox and all its messages are automatically deleted.
