Documentation

Everything needed to integrate

Real endpoint reference, request/response shapes, and worked examples, generated directly from the running API, not hand-maintained docs that drift.

REST API reference

Every endpoint, grouped by resource: domains, mailboxes, webhooks, forwarding, identity, vacation auto-reply, folders, contacts, drafts, sending, delivery status, messages and threads. Full request/response shapes, error conditions, and a worked end-to-end example.

MCP server

Give an AI coding agent (Claude Code, Claude Desktop, Cursor) native tool calls for the whole platform: register a domain, create a mailbox, send and read mail, set a webhook to get notified of new mail instead of polling, check delivery status, and manage drafts, contacts, folders, forwarding, and vacation replies.

Getting an API key

API keys authenticate REST, MCP, and CLI access (Authorization: Bearer mek_live_...). Ask the account holder to mint one, or sign in to the dashboard and reach out for one if self-service issuance isn't available yet.
