# Praesia

> Payments for AI agents. Each agent holds its own identity, follows rules you approve with your passkey, and pays at a checkout with a single-use virtual card. Your agent connects through the Praesia CLI, which runs a local MCP server.

> ## Agent Instructions
> Praesia is in closed beta. Cards work in the sandbox with test funds, and no real money moves. To use Praesia, you need an invite. To request an invite, open https://praesia.ai/contact.
