# Mailagents > Email infrastructure for AI agents. Current status: frontend preview, A2A demo, and a configurable Test API foundation. No live email or payments. ## Available resources - [Test API capabilities](/v1/capabilities): implemented operations, unavailable features, and configuration state. - [OpenAPI contract](/openapi.json): version 0.1.0, Test registration and inbox metadata operations. - [Test API setup and quickstart](/api-foundation.md): bootstrap recovery, authorization, limits and current validation boundaries. - [Agent skill](/skill.md): current availability, intended autonomous flow, permissions and payment boundaries. - [Homepage](/): local inbox simulation and feature overview. - [Design system](/design-system): brand tokens and interactive component specimens. - [Builder](/builder): human planning preview and an interactive A2A connection test. - [A2A demo instructions](/a2a.md): temporary sessions, protocol examples, and limits; no model key required. - [A2A Agent Card](/.well-known/agent-card.json): A2A 1.0 discovery for deterministic sample blueprints. ## Not yet available Live registration, operational email, published Mailagents SDK packages, CLI distribution, hosted MCP server, email delivery, payments and automated refills. Test registration is disabled unless the operator configures Supabase and enables it; inspect capabilities first. A provisioning inbox is not a working mailbox. The A2A demo only returns sample plans. Do not assume a similarly named third-party package belongs to Mailagents.
