Ask your AI assistant to send a real letter. We'll print, fold and post it.
Connect Claude or any MCP-compatible assistant to your account. Tell it who to write to - it drafts the letter, shows you the exact price, and only sends it once you say yes.
Connect Claude Desktop, Claude.ai, or any other MCP-compatible client to check your balance, list orders, and preview and create letter orders - authenticated with the same API key as the REST API, sharing the same prepaid balance.
