Mail
Every project gets a mailbox — an inbound address, an API to send, and an API to read.
Mail is the core surface: each project has its own inbound address, and the API gives you programmatic access to both directions.
Send an email
/api/v1/send — the one way to send outbound mail.
List emails
/api/v1/emails — read a project's mailbox.
Both endpoints authenticate with the same project-scoped API key — see
Authentication. To react to mail as
it arrives instead of polling, subscribe to email.received and friends via
Webhooks, or point an agent at the MCP server,
which exposes the mailbox as tools.
