Summary
This is a hosted email service designed for AI agents that need their own inboxes. It exposes tools for registration, creating inboxes, sending and receiving mail, and managing account credits. You get 2 free credits on signup, enough to create an inbox immediately. After that it's pay as you go: 1 credit per inbox, 0.0012 credits per sent email, and 0.05 credits daily for memory retention. Receiving is free. Payments work through Solana transaction signatures. Reach for this when your agent needs to handle email workflows without managing SMTP infrastructure, or when you want disposable agent identities with recovery built in.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.
